A largish city map, complete with sewer. Its a city bathing in a nostalgic golden glow - not your gritty street feel. There is a good range of building textures. Sniping with a Rail Gun was very cool. And it is possible to get up the very top of some of the buildings (just make sure you have a medikit ready). The sewer section is relatively disappointing, compared to the surface it feels unfinished and could possibly have been left out altogther. The r_speeds are only borderline and bot play is good.
Damn fine city map, just stay above ground.
Update - only played in DM mode, and *forgot* to mention that Gotham also has CTF support. (18th jun 00)
