I still enjoy playing it time to time with my friends :)
Then you will love BB2 when it comes out :) We also added new gamemodes and more to make it more interesting, and lots have been changed (except Classic Mode). We are currently re-working some areas and redoing it since it wasn't that...
The mods with custom engine "changed the HL1 engine", will be broken, if not the team is still active and fixed it. Rest of the mods who ain't didn't change the engine, still works.
Love the half-life series :) Episode 2 was very well written, and other stuff that I can't hardly tell with words :P Can't wait for Half-Life 3, or Episode 3
The best "crappy" mod for Half-Life 1 with zero awards! so amazing!
I've played this with some of my friends, was fun as hell :P
Note:
Don't use the tripmines, if you place one, everyone on the whole map dies (if you destroy it) :3 and the Tao/Gloun/Gauss Cannon is over powered :D...
This happens if you don't own the game on steam legally. If its a mod for HL2: DM, bought from steam, then Re-Install HL2: DM and SDK Base 2006/2007 and/or other content the mod is using as base.
