Well, this isn't my map. A guy named "Upsilon" at Halo 3 Forum made the map. However, this is the best FFA map (2v2 works, as well) that I've ever seen / played in my entire life. He made use of all the glitches in Forge to make an amazing map.
I don't think he's ever posted a map before because his thread sucked, so I'm going to rearrange it.
Here's my edit:
Map Name: Confined Map Download:Click Here Gametype: No specific gametype. Made mainly for FFAs and it works with all MLG gametypes. Pictures: Video:Download
Wow this map is awesome! It's like a better version of Gradient
Senor_Grunt: Okay, so, I was playing CoD4 earlier, and about 30 minutes into playing, the screen went black, then flashed, then the 360 gave me red rings. Only, they weren't rings, they were half of the ring. Like, only two of the controller light thingies were light up red. WTF does this mean? Like seriously. My 360 still works, but it does that like once every week at the least, and it's getting annoying getting to round 16 in the zombie mode for CoD5 (so totally not bragging ), then suddenly blacking out. :[ tucker933: Pour some liquid nitrogen on it.
