The coloring and look of objects also remind me of that Terminator game, Terminator Future Shock. In that game the enemies really gave the impression of being AI controlled enemies (well obviously, they were, but you see what I mean). Giant grey and red killing machines trying to find a way to walk round a wall behind which our tiny human hero was hiding. I can imagine situations in your game were your CPU controlled team members have all been destroyed and you are the only one left, and enemy scouting planes are circling overhead, and you try to shoot them down lest they give away your location. Or is that not the way it works! :)
