DarkInferno :
The character is great, it is an ennemy ? caus in FPS you don't see your character !
a few coders would help [am not the best coder however ^^]
Wel lwhat you've done so far in coding, is already very good ; i couldn't code half of what you've done !

If you need some help : model assets with UV and simple textures color (i'm not good at making textures them) , just send a message.

Will it be aliens , or creatures on your game ?
And will you use normal maps ? and baked normal map ind diffuse texture look great also and can be used if you don't plan ot use a normal map shader !
