Umm...Don't you have the gravity gun/crowbar? And it isn't limited to difficulty it seems...so that one doesn't sound too bad, especially considering how short the episodes are.
My impossible achievement is the Seriously and Seriously 2.0 Achievements from Gears of War 1 and 2. I just won't play the game enough to get those, sorry. It isn't like there is an easy way to farm kills either, unless you ride the Brumak x amount of times, but even then you get about 100 kills a run(thats for number 2). For those of you who don't know, those achievements require 50,000klls and 100,000kills respectively. Yeah...too much killing. I did the one in Dead Rising but thats because you had a freakin' car that you could plow over about 1,000 zombies per car ride. This is just unreasonable.[/quote]
You expect to kill a horde of headcrab zombies with a gravity gun and a crowbar? Even on easy, that's kind of ridiculous. Also, the seriously 2.0 from Gears was not meant for just one play through. I believe it counts in online and horde mode, along with the story mode. I've been through story mode once on Normal and got 1300 kills. More enemies in harder difficulties and a couple of plays through, a while on horde mode, and x amount of hours online, and you've got yourself an achievement.
