Good Game. PLEASE keep updating.

It's a really good app, and I like the new content that's added. The new zombies are fantastic, and the sprint button is a nice touch, even though you can't move backwards. Also, I really do like the variety in parts, especially for the rifles. I still think the best thing about this app though is using any photo from the camera roll as a weapon camo. Game has gotten better and better. One suggestion, could there possibly be more AK parts to build more variants like AK12, AN94, AEK 971, etc? Please keep updating. Best gun building app by far.



Ok first things first I love this game but all of a sudden the last updates changed my perspective forever. I love how you added the xm8 but I mean seriously, the main xm8 top can’t even attach a scope, come on! All the guns started sounding like you were banging metal onto a trash can, camera mode was removed (CAMERA MODE), and lost of all you guys should make the pistol and rifles free, it would be cool to switch trough primary and secondary during the shooting range, that’s all for now.

Overall great game though! 🤪

It's good but it has it's flaws.


I like the fact you can customize litterally everything. But can you make it where you can use recorded sounds that the user already made or has from MP3 or WAV files? Would be cool.

And the ability to litterally, reload how you could in real life, like the ability to do some frame things and a point and click movement for the arms and weapon? Would be AWESOME.

And also make it where you can have atleast 4 or 5 guns from each buyable gun pack. I feel lonely with only the Rifles. :(

And the ability to use device's camera for the Video Simulation. If it's already on it, show us how as I am unable to use Video Simulation with my camera.

Fix/Add these things and I give it a 5/5 :)
