XDM is an high-quality Unreal Tournament-style Half-Life 1 modification. XDM features Classic Deathmatch, Team deathmatch, Capture The Flag, Domination, Co-Operative, Last Man Stanging, Singleplayer game rules, new weapons, new high-quality maps, new hi-def models and lots of special effects. It is an Unreal/UT-style HL mod with tons of familiar stuff and atmosphere. 8) XDM continued where VALVe stopped. It provides extended features, effects and principles with FULL BACKWARDS COMPATIBILITY. XHL pushes HL engine to its limits, don't underestimate the GoldSource! XDM - brings unreality to Half-Life since 2001!
A map (dev name CTF_ColumnsXL) which will probably never be finished.
Requires mapping skill: over 8000 (almost have it :) ), time: over 9000 (don't have it :( )
Also, this shows how I map.
That is impressive!
