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!

I remember having asked Ruca about why the SL8 got removed, he said it was because the models was bad.

Hello guys. I must say - it's real good thing that you're returned MP5K and Combine Pulse-Rifle X (MG1) in game, but why don't you make some new good stuff for them? I mean, new normal map for MP5K with #phong and other. And why don't you make MG1 view like the Mounted Gun from Half-Life 2? Because that "pulse_mg_ref"... it looks real ugly. It was good on Source 7, but not now. Seriously.
If you interested, I have already made the new normal for MP5K, updated MG1 textures (also HD "newstock") and added new .vmt files for STUNSTICK and S.L.A.M. (it looks good with phong).
I can upload it to you, just yell. And, Happy New Year guys! ;)

Since moving to the Steam version, this feature is not available. However we are looking at a new system for next year.

Hey, since some features got removed for Steam integration, the SL8 was removed because the texture was low resolution, any chances of adding it as a custom weapon for custom made maps?

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.
