Would it be possible to have the changelog on this site right under the download button? im currently on 20220508 and new version is 20220508.1 .. seems like a small update, and i dont wanna bother downloading it for a small patch.. i would need to download it and see the changelog.. perhaps there is a bugfix i needed but wouldnt know is there? just a suggestion


Good idea.  In the meantime you can check gunnerheatpc.com for the latest changelog.

Will you support raytracing & HDR? Seeing the shot lighting up the darkened terrain, explosions casting shadows, I'm getting goose bumps just thinking about it. 


Is there a way i can become a game tester? i would really like to see this game grow and i want to help out the developers by providing information on the game

There is not a dedicated tester role.  If you would like to provide feedback, there is a #testing-feedback channel in our Discord server.  It includes a link to a public bug report page as well.

This version is smoother than the previous one,  i wonder what is the vehicle you will add to the empty concrete ramp behind the Bradley`s one!

I think it is ... M1A1/2 ... or ... BRDM-2 AA/AT versions ... or ... BMP-2 ... or ... Shilka ... or ... Jeep?!

anyway thanks for your efforts, amazing work.

Thanks for this latest update and bug fix! We see great progress.

I have a few questions and tips:

@ If an enemy vehicle or weapon is behind an object, will it be possible to destroy or damage that object (e.g. with a HE mine) to expose it and then attack it?

@ Will the map be better used and useful in planning? I mean the following:

Did you plan to be able to put our own markers (at least a simple “x”) on the map and maybe mark the position on the map to coordinate and issue orders to our unit if we have the role of commander? Maybe even with a view through binoculars to a certain area we can accurately mark it on the map.

@Maybe we could calculate the distance on the map between different positions, markers or landmarks (with a ruler?) for better planning of tactical movement.

@ I know it's not possible now, but... If our tank or armored vehicle is just slightly damaged, could it be repaired somehow? Too bad if only one tank caterpillar was hit that for us the war is over. Let's say another vehicle comes near him and waits for a while (like ammo transfer and restocking). I know it's gambling and it's dangerous to expose our other vehicle to enemy fire but it could increase the tension of the war, but at least   -   "We don't leave our mates behind" ;-)


Do i need to still pledge to update the game? I've ran out of money on my bank and i want to update the game, but it says i cant because im not pleding.

In order to access the Patreon demo download page, you need an active pledge.


If I support the game on patreon does that mean, once the game is released, I will have full access or would I need to buy the game?


We have not yet determined what rewards patrons will receive when the game is released.

Hm Why did my antivirus said this is a virus(or threat)? I wanted to play this game


Many players have seen false positives from antivirus software when attempting to run the game.  This will happen until we submit proper software signature stuff.  In the meantime, we promise there's no virus and you can manually allow it.


I am a new Patreon, how can I activate M1 & M2 utilisation in the Demo?

You will need to use the separate Patreon demo.  The link to access it is in your GHPC Patreon welcome email, as well as every release notes post on Patreon.


This is a great game thus far. I hope you guys don't turn it into a World of Tanks or War thunder theme. I've played a lot of tank sim games and you guys are spot on for a great platform, like DCS. Keep up the great work and you will have my support in the future. Hooah!! Drive On!!

I think in some places on the map there is a small problem with the texture. As you can see on pics. there is no one in front of me (only terrain, mud...)  but if I turn on the IR, the targets are visible as if they are not below the horizon level. Sometimes, even without the use of IR, an enemy vehicle can be noticed in motion. Barely, but you can still see the movement! Then it's easy to just wait for him to "come out" from behind "something" and fire a shot. This could serve as a hack-wall cheat for someone, especially "dangerous" if there is a PvP mode online.  Sorry, I can't send more pictures at once.

This is "Fulda Gap-Legacy / T55A Wave"


It's a little frustrating when you win a battle but lose the war, and the tank turns upside down just because... So, it always happens when the tank just touches enemy weapons. You see what it's about, right? ;-)


This was my war that never happened. Stationed in W. Germany with the 3rd Mech Inf at Schweinfurt in the mid-late 80's.  So many assumptions I had about that what-if war are open for reinterpretation since Ukraine. We all assumed we would be "speed bumps" for the Pact armies on their way to the Rhine. I did have one Col. who stated "You're all going to be surprised. The IGB (Inter-German Border) is going to be the world's largest Russian tank junk yard in about 48 hours." We didn't believe him, thought it was just tough talk to perk us up. After Ukraine though, maybe he was right??


Well, the fact that "your war" never happened is probably the reason you're still alive and (at least parts of) Germany is not a nuclear wasteland.. I mean what your Col really meant to say is "You're all going to be dead along all those Soviet (not Russian) tanks anyways" - You know the US deployed Nuclear Land Mines among others to stop the Soviet tanks when invading through the Fulda gap? Fulda --> Schweinfurt = less than 100km.. You'd have been right in the middle of that mess.

You see, there is a difference between the Soviets and the Russians. The Russian's economy and military is messed up since the dissolution and is trying to recover. While the Soviets maintained a wholesome military and economy. (until just before the dissolution)


really loved it, keep up the good work team, however my potato pc cant keep up with it, yet enjoyed it. :)

this is molten gold baby cant wait got my $60 ready


Hello :-D
I just stumbled upon this game and damn its just what I wanted since years. I hope it turns out well.  Please also focus on lower end pc-s in final product if possible :-D it would be really awesome to play without some gaming setup.
A question though. I know it is far from being optimized, but maybe you could add a map with minimal vegetation (desert or snow), or even just without grass. Even this version would run much smoother without all the forests in the maps included.

Keep it up, it really looks promising now!


There hasn’t been a good tank simulator in a long time, and this project is a real refreshment. For now, while it is in the demo version (and in the finishing phase) we see in which direction the game is developing and I think it will become the new leader in the tank simulator. I hope that the developers will keep the important concept they set when creating and that we will not see buses, race cars, flying bikes and tanks or similar stupid user creations on the maps. It will have to be banned. The only thing that has to fly in this game are the turrets of the tanks and cannon grenades!  :)

Although it is good when we have large spaces on maps in such games, we hope to get a quick-mission editor to create our own online or single play missions as this will keep this title on the scene for a long time with diverse and never boring, predictable or repetitive gameplay options...

When it will be possible to play online, the creators will have to make very good protection against cheaters and you know,  sometjing like exploits, wallhack and modifications , because otherwise this game / simulator will become just another quickly forgotten title. Thanks developers for the effort!

когда обнова? Очень много багов исправьте пожалуйста!!!

There are a lot of improvements with the last patch. It is interesting when a crew member reports "something is strange ..." :) and will be fine with  more interactive voices of the crew who sometimes scream or panic. And there is a lack of background "war sounds", distant detonations, explosions, machine gun bursts, etc.

You might consider implementing an auto-throttle also by double-clicking the "W" button. In the tank, in addition to movement, constant searching for the enemy and aiming is also important. there is a lot of different work! We have to move our finger off the trigger to speed up or slow down the tank and seconds are crucial! You know that in war a soldier must always have his finger on the trigger :)

BTW, great progress for now!

(1 edit)

There's a sort of autopilot, you can press F4 and it'll show you a green circle left click and your tank will go there in a straight line.

You can also press + and - for "cruise control", cehck your keybinds in the vehicule section.

Where can we post suggestions or bug report ?
(btw, would be nice to have a "night mode" for the proving ground)


you can accelerate and reverse the time of day with a key combination, I don't remember it though

its , and . or its one of those keys near this area not certain

(1 edit)

With  Full stop (.) and period (,)    key


The Discord server has a channel for feedback, and you can view or submit bug reports at https://github.com/RadianSimulations/ghpc-feedback/issues

You can change the time of day in any mission, including the proving ground, with the comma and period / angle bracket keys.


ok, thanks!

keep up with this amazing work


Amazing game, would donate to Patreon if I could.  Especially love the fire control mechanics implemented, keep up the good work!


compress the game please, my internet is limited


Love the game keep it up!!


Okay, before we start any mission we have a briefing. We get basic instructions on what our task is but also in which direction we need to go. In addition, we have at our disposal a map on which we can approximately determine our position with respect to landmarks. The problem is with orientation in the "field" if you do not have a compass or a map. I understand that this is a demo and that after starting the mission we do not have a map for now, but we should still implement at least a compass to be available in HUD. It is possible to navigate the field only if you initially follow one of the vehicles from your unit. But if you separate yourself from the group, in a few moments you won’t know where the action is because you don’t know in which direction to get to the battlefield (especially on night missions!). 

In the end, if you do not understand where you are or in which direction the enemy is and from which side you can expect him, the mission comes down to driving and wandering around the map. 

BTW, in short, I speak globally from personal military experience.


The game isn't done yet, and everything you mentioned will be taken care of.

Yes, I hoped so. Thanks for the information. Keep it up!

Is there a way to disable the mouse acceleration when aiming through the tank sight?

No.  The mouse controls the intensity of the traverse/elevation rather than the aim point itself (kind of like moving a joystick), so to "disable" that would change the entire principle.  We've implemented it this way because modern fire control systems with lead adjustment would hardly work with twitchy FPS-style mouse aim as seen in many arcade tank games.  

If you're having difficulty learning the GHPC aim system, we recommend turning on the "show input" option in the settings.  The arrowhead is controlled precisely by the mouse, and the arrow direction/length represents how the aim point will move.  It should become intuitive after some practice.


I see. This style does help a lot with tracking moving targets actually but it's kind of horrible at moving to new ones. When switching targets fast, I end up overcompensating or overshooting the targets. 

Would you consider a switchable aiming system that frees the mouse and let the turret catch up to its position? Players could get the best of both worlds by using this to quickly aim and the current system to track moving ones.

We've thought about things like this - but it's something we probably won't be revisiting until a bit later in development when we're doing user experience (UX) and other polish items.  Appreciate the suggestion though!


You don't get what he's saying, this game isn't meant to have a War Thunder type of control system, this is meant to replicate a realistic fire control system in a tank. It's supposed to take practice to get good at. 

There's no way to stream over discord. Usually an option pops up to directly stream any other game on discord, this one doesn't work with that. recording the screen itself of course yields no sound, and only shows desktop anyway if I'm fullscreen'd.

We'll be adding Discord streaming abilities later.  In the meantime, you may have some success manually adding the game in Discord settings (it may need to be in windowed mode to be detected).  After that, it should be possible to stream it (but you may once again need to put it in windowed mode for a moment to get it detected).  Another method if you've manually added the game: pop up Discord's stream screen/app selection box, return to GHPC, and then tab straight back to Discord.  GHPC should now be in the list of choices for screen share.  


You deserve to get rich, because of the effort you put into this type of simulator! A whole new way of tank simulation. It is obvious that there is still a lot of work to be done before the final version, but for now - great! Many thnx!

What is this aiming system? When I bring up the reticle it feels like Im trying to aim with a touch pad. This game is unplayable with controls like this. This feels a lot worse than the last snapshot I played.

as spy once said: "Magnificent"


I've been waiting for years to have a decent SP tank fighting game, thank you so much for all the effort you put into this! I will see about supporting you on patreon soon.


This game is a work of art.. I look forward to the future of it I can tell this has a ton of potential.


When the optimization will be made? i am having serious heat issues (80º celsius) on the GPU with the game, even on very low graphics, my drivers are clean and very optimized, i have a GTX 1060 and a Ryzen 5 3600 and 16 g of ram.


Optimization is an ongoing process, but there's only so much of it we can do in this stage while actively adding and changing things to build the game.  If performance issues are severely affecting your PC, the only solution for now is to wait.

try turning up your gpu fans with msi afterburner 


How much will the game cost when its launched on steam?


That information is not yet public.

Having a bit of trouble opening the game, i have downloaded itch and the game but i can't access it as it doesn't open when i launch it could i have some recommendations on how to fix this problem

Some people have antivirus software that silently quarantines things.  Check if you have this, and if so, add an exception and re-install the game.

ok thanks!


I have been playing this game for the greater part of a year,

No complaints or comments just wanted to say good work and thanks so much.

id also like to point out the download is 1.9GB , so you could atleast update that, i have downloaded lots of these free versions, as an archive, not all of them, but i have 7 now, from the first one as well


is Abrams and T72 avaiable in the demo yet or no?


You need to be a patron supporter if you want to use the Abrams or T72.
So sadly not yet.


The Dev is friendly. I clearly can see a potential that this game gonna blowup someday. But really can' wait for the steam one!!! I don't have credit etc yet to support the dev on Patreon sorry bout that.

(1 edit)

will nutral steering and the dead zone over the back deck the "NATO hump " be implminted on abrams and m60?




After looking at some gameplay, I'm wondering if the interface that informs about hits on enemy tanks can be removed, as well as other HUD elements in general.


HUD in general is likely to change dramatically at some point prior to release.
