Yeah but the real question is did you ask for people to help you get the achievements or did you get them legitimately? I.E. "Hey guys anyone wanna help me with Overkill achievement? Uh...I'll help you guys with any you need..."
see some guy named ignoranthawk on GTA IV and thats my cuz.
HE PWNS!
Haha that's the same with me too. I got a ton of achievements in a Swords on Lone Wolves game. Bottom area of Snowbound + Invisibility + 5 other people down there = win for me. I know I got Steppin' Razr and Overkill and I think I also got Killing Frenzy because I ended up getting Killtacular (5 kills) to add to the spree I already had. It was so awesome, but at the time I was pretty nooby and didn't even think of making a video of it in theater.Haha. I've asked for help sometimes. But I got all of my legitimately. It was my mom's birthday and they called me out to come sing happy birthday with them. I was buying for time and I was on Swords Lone Wolves. And I sliced all of my opponents at once and got about four achievements. After that, I left the game on and let them kill me. XD
Yeah, that's definitely one of the harder ones...I got mine by just getting two people who were going to melee each other. The easy way to get it is to just laser two people in a warthog, I wish I would have known that when I was going for all of the achievements, but oh well. In my opinion Mongoose Mowdown was the hardest to get, finally I got a guy at the bottom on Isolation who heard me coming and when he turned around to see stick me it was already too late and I splatted him.I asked for help with 2 for 1, but got all the other achievements legitimately. Overkill was a nightmare, thank god for mosh pit on legendary brawl =]
And I have another one, where I threw a grenade at all four enemies running at me, it blew up and killed two of them. The little bomb boxes placed around the place blew up and wiped out the other two guys. XD My little 9 year old teammate was all, "OMG YOU'RE SO AWESOME"
