I'm off to a lan party on friday, it's gonna be huge, and the HaloPC tournament shall be a breeze. I shall buy a new computer case there, and win the HaloPC tournament from the current champion (me bud NPC, he's not nearly as good as me.. I still can't believe he won last years tournament), and force him to install the lights! bwuahahaha! man I'm cruel when it comes to gaming on HaloPC. 9_9
The best part of Halo in my opinion was the coop campaign mode, but they took that out of the PC port for some stupid reason.
If you're going to try it, rent an XBox and make sure you have someone to play it through coop with you. I found the deathmatch and SP campaign pretty boring otherwise, but thats just me.
