Me and Ballistic started this a few months ago, but I recently decided to finish it.
It's MUCH more open than both Bloodgrounds and the original. I will admit that I took a few liberties with the layout (stairs are too mainstream, pillars are more fun as wallrunning columns, and big unobstructed windows are pretty)
I decided to go for a sort of "old bricks meet future tech" theme. It really was an excercise in /vcolor for me; you might notice a lot of the bluish philipk textures were turned yellow or orange, such as the concrete texture mainly used in the map.
Playable for (T)DM, DTF, and CTF, but preferrably ffa deathmatch.
