Still not dead
HL2DM.pro was founded in 2016 to support the Half-Life 2 Deathmatch community, with a focus on reviving competitive play especially in Australia/NZ. Our servers are open to all and our community is friendly and welcoming. We now operate at least one server in most regions, and our match system (XMS) is open source, so you can host your own if you want.
Match reports and demos can be found in Discord. This site just contains player stats and some useful downloads - including a huge collection of maps. We also host a mirror of the original HL2DM University website.
I'm new to the game - how do I get started?
The best way to learn the ropes is to start playing! Aside from the introduction of the gravity gun, HL2DM's core mechanics are not much different to other FPS games of the era, so you can jump in and have fun immediately. However, there is a significant learning curve before you can compete in high-level matches. You may find it useful to browse through HL2DM University, and watch some pro gameplay on Youtube. Above all else, introduce yourself on Discord and you'll find people to play with and learn from.
