Fast multiplayer action set in the Half-Life 2 universe! HL2's physics adds a new dimension to deathmatch play. Play straight deathmatch or try Combine vs. Resistance teamplay. Toss a toilet at your friend today!
I REALLY love this game, it takes HL2 weapons into a new physhics system, while brings the hole thing to Deathmatch, a multyplayer game. And it has support for User-Conttent, custom maps (can be downloaded by entering a server, and has some useful ways of not bugging the game with most server-side plugins. All that, and it still keeps the Source engine running fine.
HL2:DM was awesome because of servers like Alley Cat Clan [ACC] and Manni's Fun House, but all these great servers are now down and the normal HL2:DM gamemodes are boring.
I loved playing on the ACC server (best COOP-Server) and the MFH server (best Puzzle-Server) but since they are both down I play HL2:DM rarely.
10/10 because it was a cool game once. Now it's more like 5/10
