Also featuring old and new weapons, new high-quality maps (some of which were created by TWHL members), new hi-def models, flexible network code*, lots of special effects with no hi-end hardware requirements. XDM offers full set of customization options: HUD/GUI colours, chat, team names and colours, weapon slots, translatable strings.
