Released a couple of years ago on Hotline, finally being added to the Archives. A pretty straightforward multi-room map, with a bunch of teleporters to move you around if you don't like taking the long way. Only real problem is that the teleporter pads are quite small... hard to hit 'em right if you're being shot at. (Maybe that was the intention, actually.) One of the rooms is shaped like a baseball diamond, hence the name. Them TI textures are purty!

A small net map with a raised platform surrounded by a dark ring. Carnage rates should be high with almost any number of players... there's nowhere to hide. (Weapons and ammo are plentiful.)

A small map which uses the Evil glyph textures to suggest the inside of a pyramid. Weapons and baddies galore... but flow is a bit constricted (tbasically, the layout is a series of rooms, linked by a single passageway in either direction). Rooms are either pitch black (gotta love those devlin eyes glowing at you) or brighly lit. If you know the secrets, there are ways around without dealing with the baddies.

A pair of maps that share a similar overall layout, but play very differently. Both are loaded with eye candy (Tempest, especially, has some pretty fun lighting effects), and both have a generally square layout with an outer corridor enclosing an inner complex... but the inner complexes are very different.
