From Halopedia, the Halo wiki
I mostly take a backseat to editing. I prefer to read the info since I love the Halo universe and make changes when necessary. My current Halo 4 avatar:
Winning the first round of a competion in Halo CE. The competition was held at a gamestop during the release of Halo 2 and the first round was a 16 player free-4-all on blood gulch. I stayed in one area and killed anyone who spawned nearby winning the match and bearly died in the process. I didn't win the next round (on different level w/ 8 players) but still it was a moment to remember!
Getting my ass kicked in a 4 to 4 Halo Anniversary multi player team match. Two of my teammates left the game leaving me and another against 4 others. Two players on the opposite team were really good and killed me by constantly double teaming me.
I'm a big time fan of Halo and was even considered a Halo god when playing Halo CE. I'm no longer a god but of course I still love the series!
