Medium-sized nightclub level with several dancefloors, bars and VIP areas. Comes with an optional start map, a few external textures as well as a custom skybox, and some music tracks. The map source is included. This map requires the Malice TC.
A beautiful base map that shines with graphical perfection. Gameplay is ok (only grunts and enforcers plus a few rotfish) and very straight-forward (no keys).
Small medieval outpost with a unique texture theme and horde-based combat. A touched-up version of an old deathmatch map converted for SP mode. Comes with a custom skybox.
Three independent levels connected by a start map.
Voidscape: Very small rocky island floating in space.
Brownie: Small medieval fortress with an atrium and tower areas.
For The Love Of Evil: Large Metal/runic map with majestic halls and various traps. (On hard difficulty, the map exceeds the max_edicts limit, so it requires a source port with increased limits).
