Warped Bay
RR: 8.0
This is a small map by SLAM, largely (and quickly) built to test out his brand new "Whompage Arena" texture pack (included in the download), which has been made for a new game-style that Boom has been working on.  As you can see from the screenshot, the main new texture looks pretty good, a nice believable NAB surface.
  There isn't much more to the arena than what you can see; the pulsing green glow-column is not a "healpod" but a teleporter, to whisk you up to the higher level; there are a few weapons towards the edges of the room, obscured by the pillars.
  So, a small arena, for 2 or 3 players perhaps.  I've not had the chance to play it yet, but the architecture is suitably realistic.  Not one of SLAM's most desirable maps, but still worth getting!
