Synergy is a Half-Life 2 co-opertive multiplayer modification. We have evolved from multiple mods (DC Co-op 2, Dev Co-op and Tim-Coop) to offer you the greatest co-op experience. This modification strives to give Half-Life players a true Half-Life 2 cooperative experience. The mod features our own levels and the ability to play the Half-Life 2, Episode One and Episode Two campaigns co-operatively. In addition, you can add more content by installing third-party mods, such as ROCK 24 and MINERVA: Metastasis, then playing them in Synergy!

Great laughs were had. I've met some strange people. Incompetent folks who accidentally team-kill the most competent player on the server who was taking down a chopper which fell down upon unsuspecting players. I saw trolls yapping on the mic entertaining us with great commentaries and trash-talk. I don't know how it is now but for me, that part is over. Maybe I'll come back to it, I don't know.


This mod gives emphasis how wacky we are in the online world and it does so in an entertaining way. The players will do their job, you do yours and this mod will become the best comedy you have ever seen.
