Valve's planning to release a Counter-Strike: Source version of classic map Militia described as "a fairly major reworking of the original level", featuring HDR-polished visuals similar to those of Half-Life 2: Lost Coast and the recent re-release of CS map Nuke.
Militia certainly qualifies for classic status around here. We still remember the days of racing up to the roof with a rifle and waiting for bright young CTs to edge out of the tunnel into our crosshairs. Ahh. Almost as fun as tossing grenades out of the window when they were trying to sneak the hostages out of the front door.
In a Steam news update late on Friday, Valve also said that it would release a rebuilt version of the Kalt map for Day of Defeat: Source. The wintry map features a bit of custom rendering work to help render the snowy environment believably.
Both DoD: Source and CS: Source are available via Steam for $19.95, or as part of the Source Premier Pack for $59.95 - the latter also includes Half-Life 2, HL2 Deathmatch, Lost Coast and Half-Life: Source.
Valve also noted that a demo of Rag Doll Kung Fu, reviewed last week, is also available on Steam at the moment.
