So now I find myself with Crysis 2, and despite the issues that are sadly still present, I enjoy it a lot. I'm not even that terrible.
But of course I've already found another enemy-type to damage my calm:
Energy Transfer (III), Stealth Enhance (III), Mobility Enhance (III), mostly combined with the Silenced Marshall or Silenced Feline.
You know, those guys on Crash Site that do nothing but run around in stealth, run up to someone, shoot them in the back, stealth again with their now fully recharged nanosuit and run on off to do it again and again. The guys that do not get a single objective point, but 20 kills while their team still loses. They're not squirrels, exactly, more like baboons. Crazy, rabid, squirrely baboons. On Speed.
Now it might be that I just find people irritating that do not even try to participate in the actual game mode, instead seeing everything as TIA and try to bolster their K/D to compensate for their lack of visible genitalia, but I'd like to think I'm a better man than that (despite what my second grade teacher told me).
So, what are your most hated enemies? What do they do, how do they do it? Or are you just so damn good, there's no one coming even close to annoying you, ever?
