Nuclear Map Pak v1.0.1
The focus recently has been on solo levels, but this is a pack of 26 consistently very good net levels. These guys like narrow raised walkways and sharp corners, but overall, flow is great, texture choices are very tasteful, and weapons are plentiful. There are some very cool tricks (I liked the stairways on Pseudo Bridge a lot), and nice lighting on several maps. No matter what size your group is, you should find maps you can die in here...The only downside is that they're actually asking for money if you like the maps. Update fixes a couple of small bugs (one net level didn't show up in the Gather window, that sort of thing...)
