Jeremy Condit's net maps (4 of 'em), converted from M1 and enhanced. These were great levels for M1 (usually with some sort of unusual twist), and he's really improved the feel of them for M2. Stop the Press!, for example, doesn't feel so claustrophobic anymore, now that the outer ring is outdoors... These are all worth a look. And read the readme... there's quite a bit of useful information there. Update fixes a bug, and adjusts ammo...

Very geometrical, seems to take a lot of inspiration from Bungie M1 maps (I was reminded of What Goes Up, and Bob-B-Q, for example). Great flow, and the single 1x recharger provides just enough temptation to get your buddies blown away.

11 maps. Not my style at all... well, the last four maps are okay. (The last two are actually pretty fun solo.)

5 more... a mix. Launching Pad is great, but really slow on slower macs... and there's a map here that reminds me how much that Alien textureset hurts my eyes.
