Thanks to the guys at #opus on freenode IRC for helping me use their libraries. 
Sorry if I forgot to credit anyone... please email ika4994@gmail.com to contact me.

Maybe some of the sounds credited are not in the game, but were considered. I dont remember evertyhing.

None of the art was done by me (Ika). Some of it was ripped off fourms and free texture
websites. (some basic edits of the textures and more basic textures were made by me).
Some of it was made by nogames
If the image is 128x128 then I ripped it. If it isnt then its made by nogames.

The gun models were made by nogames.

I worked with nogames while making this game. Anyone else in the credits, i didnt interact with.
