At one point I was playibg maybe about 1 hour a week of computer games. I was just going out with my firnds all the time having fun at uni.
Then I started playing City of heroes, and mercenaries for the Xbox and it ****ed up my life. ;(
Yeah their behaviour was really cool, you get the impression they really want to get to you but they are just too afraid of that thing.
I think they added that fairly recently, as the bink of the coast didn't have those on it.
Did you forget that there is also a 'hard' difficulty setting. Try running across that sand on hard and I can guarantee you that you will be owned.
It take 2 close range shotgun blasts to kill and antlion on hard, and they can kill you in about 4 hits. So take on 7 and you will not survive...
