Working on my 2nd sig..Any render ideas?

Well this is my second sig (WAYYYYYY Better then the 1st one was) But i cant think of any games that would look good as a render for it.. Any ideas would be nice:)!

alien vs predator?

Yeah, I can't think of anything. I usually pick a render then make the background to go with it. Maybe the main guy from Chaos Legion? His name is Sieg Wahrheit (Yes, it's the correct spelling).
