The bases consist of a series of steps which are covered in health packs; this made it kind of easy to invade the base (as you would just run over the health on your way up). The middle area between the forts is pretty good, but a few more clip brushes could have helped to improve this area, esp. near the boulders. The biggest problem I had was the sky texture was missing.
Its a classic 2fort layout, The base is missing a bit of stategy. Best with 6-8 players
