Its easier to program one-hit kills than an AI capable of engaging 5 opponents at once. Not sure if this counts as Fake Difficulty though, or just The Computer Is A Cheating *******. Still, I doubt its something that will ever be removed though, as otherwise the only challenge in STFs is keeping your team coordinated.
Hmm, won't let me link to a web page if the page url contains a word killed by the profanity filter. Well, replace the asterisks with a boy born out of wedlock and it works.
it is fake difficulty because cryptic cannot program anything as sophisticated as a human brain, which is why I prefer PvP.
