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). 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 cooperatively.

In addition, you can add more content by installing third-party mods, such as ROCK 24 and MINERVA: Metastasis, then playing them in Synergy!

We're looking at re-incorporating them once we find someone who's able to do it. There hasn't been an official announcement, but we're looking for level designers, modellers, animators and more to revive some of the older things, and make create new features. Right now it's a bit hard to get work done without the proper artists.

On the other hand, I'm currently working on a new map with several more textures coming up.
I'm hoping that someone will be able to put the custom textures to good use.

Probably the most epic game everyone has to try though is Syn_Trials. It is awesome.

Synergy was once the best Coop mod out there. Before it went to steamworks.

Before it went to steamworks it had awesome maps, badass new guns, custom player models, lots of other things, but then they went to steamworks and it unfortunately got bad. They ripped everything off it and left the custom player models just to donators.

The only thing I still like in this game is the "Trials" pack of maps. Only good thing left in it.
