Are you talking about the n64 game? I never played it and actually found out about it halfway through the development. I was a little disappointed that my idea wasn’t 100% original, but oh well.
NPC’s in the singleplayer are going to be other army guys (tan ones) lots of cool bosses as far as vehicles go. But for the survival maps I’m going to have a lot more varied opponents. I’m planning on an ant hill one, and a cat wouldn’t be a bad idea!
