Just played this game with my friend, we laughed our asses off while nuking ourselves multiple times. In one of the games we both nuke each others and ended the game with empty globe. 9/11 would play again


This game is actually really addicting and kinda destorys friendships.

Haha, really cool to see that the game still gets played. Thank you!

IT can get crazy with two players. Quickly it can turn into a button mash party. Funny little game. Thanks for making it. I hope you enjoy our little video.

Thanks for playing! Did you play the 1.1 build of the game? Because it seems that the framerate caused a lot of problems with the physics and the sizes of the shields probably because you used the Fastest option in the Player Settings, which should have alredy been fixed with that update.

I think it's the decade old laptop we're playing on. I'm not sure which build it was at when we played. After a recording I tend to uninstall to keep the drive free.


At least it worked and you had some fun with it. Thank you for the video!

Glad you enjoyed the video!

can i monetize videos of this

Thank you!


Thank you for this game!! I spend a good time with my brothers!! Hilarious for four players! Could be a good idea add more players...

Thank you! Those words mean a lot to me!


Simple idea, yet addictive game. Some online multiplayer and AI might boost the game to a new level.

Thank you! I'm currently missing the motivation to continue working on this game, but I will definitely keep that in mind.

Does the game have gamepad support?

You can configure the controls in the unity player configuration input panel, which starts at the beginning, but the default controls are keyboard only.

Can you make an x64 Linux version of the game?


Hope it works:


It didn't work unfortunately, I got this message (in Dutch :p):

'Er is voor bestandstype 'uitvoerbaar bestand' geen toepassing geïnstalleerd.
Wilt u zoeken naar een toepassing om dit bestand mee te openen?'

It basically says that there is no program installed to support this executable. I guess the computer doesn't know that the executable should run on itself and use the data from the folder.

Thanks for publishing a 64-bit version, though.

I'm using Ubuntu 14.04 btw

Right click to the launcher, propieties, permissions, launch as an executable.

I tried that. No succes unfortunatly. :(
