It's the week for solo scenarios, I guess... Here's a four-level spinoff of the Bungie universe. Map design is quite good on all levels (there may be some problems for 040 players on level 3-too much stuff). The story progresses well for the first two levels, then seems to become a Bungie derivative (I felt like I was listening to a juvenile Durandal). It ends with a bang, though. (You are gonna get SO lost on level 2...)
