Omg, omg, omg omg!
Finally got my last and final Achievement in Halo 3 after 3 months of 995 Gamerscore! The agony.
Cool thing was, once I finally got it it was even in a normal Slayer game... Not a Swords game or anything.
Hilariously enough, that means 3 Overkills in 3 days, people. Only this third one was Ranked Free For All, which is what it needs to specifically be for the Achievement.
Here are the game stats. Whoo!
Also, if you want to watch the clip (assuming you have Halo 3, lawl), you can download it on File Share slot 14
here.
The reason this is a big deal is because, as many of you may know, people boost ALL THE TIME for Achievements that restrict you to Ranked FFA, particularly Overkill and Two For One. So yeah. The fact that I didn't boost for any of the Achievements = awesome.
