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!

Greetings everyone! We have another update for you all! Before we get to that though, I'd like to invite you to join us on Twitter; we'll be keeping in touch with more development news there. Follow us! For those generous people that have donated to this game; we've added two new playable characters for you to use!

We've made some fantastic changes to the Create Server dialog window; images of the map, as well as the name, are displayed in a scrollable window - to make it easier to identify maps. Take a look:
Now if you'd like to review our full change log, you can do so here; Version 28 ChangeLog. As you can see, quite a few bugs have been taken care of as well. Try it out, tell us what you think!

how long until next version, because i donated ;)
What's going on with your website? www.synergymod.net
Well somethings gone wrong, and the moddb page is very slow so maybe we should start group chat on the official group.
So does anybody know what happened to the website?
Working on it.
yea I have a question will you guys be adding some custom weapons to the mod? like say some of the cut weapons for example like the smg2 AKA MP5K, XM-29 OICW, AK-47, Alyx gun, Annabelle, exc? Some more variety to the weapons would make the game a bit more dynamic.
Yeah some content will be returning.
The MP5K is in there.
i get realy anoying gray boxs when im playing with friends
Is there a custom player model system? and if so were do you get the models? I understand that in this update those awesome looking models are for donors only. But still is there custom models like in the old Synergy.
