A funny thought I had while playing SP on SS difficulty today was how difficult the Aliens were to kill, especially if you don't resort to sniping and assassinations. What's funny is that I find the SP campaign more difficult than playing MP online lol
I keept getting killed over and over by Aliens but MP players are a lot easier.
Is Crytek AI smarter than real people? lol
People have complained about the AI but I have played both Veteran and the majority of SS and it's pretty good to be fair. Small hiccups like they won't attack you if you snipe them, they all stand there miles away and let you kill them, but for the most part they are pretty tough and I haven't seem them running in circle but I have seem them walking into walls but that was a couple weeks back before the patch and haven't seen that since.
