first off:
you are not allowed to use the predator, the look and the weapons, for they are copyrighted.

the model doe snot work ingame. end of story. too high poly, badly modeled and in fact really ugly.

third:
jungle. really? you do know that its probably the worst case scenario for the engine to handle, a jungle? many have tried, many have failed.

fourth:
i dont want to talk down on you. i really dont. but you have to understand that what you are about to do was doomed to fail from the very instance you had the idea. and you will learn that. it does not matter to me at all if you believe me. i couldnt care less. but you will learn that i am right.

fifth:
if you want to do something, anything, first find out what you are good at and train that skill. create a small game first. do some research. dont jump into there. making a game nowadays is not like it was years ago. and even then, this wouldnt have worked...
