Yup, I've been dling mods like crazy, and I was wondering what other hl2 modders play.
My picks:
Antlions Deuce- Its only single player, which is meh. The voice acting is AMAZING! "Oh God, its ANTLIONS!" Can't go wrong with a matrix soundtrack. The gameplay is fun, but it seems impossible to beat.
Garrys Mod 8.3- The multiplayer feature is laggy as all hell, and maps take a long time to load first time around, but this is a great mod. I usually end up making destruction derbys and rocketcars and the like.
Plan of Attack- Very CSSish, but with levels and whatnot. Now that the Beta 3 is out, many issues have been fixed. I still don't like the aiming recticle, but thats just me.
SourceForts- Take CTF and smash Lego Creator on. Personally, I think its really fun, but some people are assholes and kill my defs.
I play a few more, but a lot of the ones I have are dead, or not worth mention.
