Starting this map is dangerous. You will be trapped in a 3D world that you will not want to leave. A visual delight, amazing detail, smooth game play in a 4 to 5 player DM and very cool Team Deathmatch (2v2 and 3v3).
There are two very minor, subjective, nit-picks. The flight power-up may have been better as a Quad or Haste. The barrels take too long to explode to be anything more than a gimmick, but they do add a lot to the already rich atmosphere.
There are a number of cool trick jumps. With the CPM mod expect to find many more. Bots do pretty well considering the complexity of the map.
A total blast, grab it now!
