Takes its inspiration from a classic M1 map (Pillars). Simple, clean, and small enough to be carnage-filled. Can actually be played in both M2 and Infinity (although I think I like the textures better in Infinity, for this one). One secret, but it's only a little one... mostly this is just a great place to kill people. Update fixes an untextured side and adds some sounds and minor tweaks.

A very nice bilaterally symmetrical open-air arena. Flow is great, with plenty of avenues to the various sniping ledges. Fun lighting, and a cool little term.

8 levels, mostly ports from M1 suicides (mods of Bungie M1 maps), but including Electric Sheep 2 from Infinity. Some of the texture choices hurt my eyes, but as usual, layout is great, and carnage is high. Warning-there seems to be a bunch of untextured sides (shows up as smearing). Not fatal, but...

A large level, with big open rooms joined by hallways of various widths. A large underwater area, as well... Flow is not as good as it could be, mostly because elevators are a primary mode of transportation, but they all move really slowly. Getting out of the room with the recharger, for example, is a pretty painful experience... Ammo is very scarce, for games of more than two or three people.
