hmm, Synergy or Obsidian Conflic?.....I CHOICHE Obsidian, because is look like a mod from SC.

Best HL2 COOP mod,Recommended to all the players

Best coop, for Half Life 2.

Love everything about this Mod, perfect co-op Mod!

Now I can finally play hl2 lol

Amazing mod if you want to play the Half-Life campaign with some company. Also packed with custom maps, which go from a starship troopers survival map, to tending your own farm.

Made our LAN awesome!

The mod itself, it's good.

but there way too many anime-tards playing this, ******' ruining everything.
