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,
I apologize for the longer-than-usual update, but we have been quite busy with other things. (Not to mention my motherboard was fried a while back.)
So without further delay...
Synergy version 11 is now available on Steam!
Please NOTE that Synergy REQUIRES "Half-Life 2" to function properly! If you do not have Half-Life 2 installed and fully updated, Synergy will not work.
This version of Synergy addresses issues and concerns brought up by the community and fixes some bugs.
It also adds new content - you are now able to play MINERVA: Metastasis online with your friends! (BIG thanks again to gmc.jimmy for his work with the EDTs.)

Some of the issues brought up by the community that have been corrected are:
* maps restarting when all players die,
* damage scales of player weapons being reduced,
* respawn times being too long,
* players pushing other players too hard (potentially pushing them off an edge)
Check the version 11 Change Log.
For the map restarting when all players are dead, we have plans of using an "auto-save" feature (using the "trigger_autosave" entity), much like the one that exists in the original Half-Life 2 game, then having the map restart to these auto-saves instead - but for now, the map restarting will be disabled.
The respawn times have been adjusted slightly, not a whole lot, but enough that you should notice a decrease is waiting time.
Also, I'd like to mention that while you're waiting to respawn, any teammates that die, will add more waiting time to your current time; some people haven't intuitively grasped that yet so I thought I would mention it.
There are plans to change the "floating avatars" as well. We're looking into some alternative options to this. The goal is to be able to find your teammates easily, without adding clutter to the screen and you can identify players somehow and see their current health.
If you have any suggestions for us in this matter, please feel free to post on our forums.
In addition, there are some unmentioned features that are being worked on too. One area of this is improving the effectiveness of the player healing (healthkit distribution) - increasing amount of health each kit gives and the speed at which it is given.
I hope you all enjoy the new version, any feedback you have please let us know by sending an email to [ synergymod@gmail.com ].
Have fun.

Why am I seeing absolutely zero servers on here? :(
I gave this mod a play and I must say it is fun but needs a lot more work. There are alot of bugs in it, esp the vehicle chapters.
What does the "donors features" buttton do in the synergy menu :S?
are guys going to add in the beta hl2 monsters & weapons in the campaigns? Because the sven co-op for half-life added in beta monsters and a shit load of extra weapons..
is there a way I can get an older version? I only have ep1 and now I can't play it! any sites have the download or is it steam only?
Is there any way to enable the restart map when all players die on my server? I really liked that, it made it much harder.
Next version will introduce multiplayer save/restore checkpoints.
Reock's Reveiws
Basicly this mod does what it says it does, provides half-life 2 players the ability to experience Co-Op play, there are usualy about eight or so servers going with people in them at any time, generaly these servers are running official games (HL2, EP1, EP2) rather then any custom maps but the option IS there and they do pop up occasionaly. I use synergy in conjunction with obsidian conflict to give me a fairly respectable play field with co-op play, OC tends to lean more twards co-op maps and I'll have a comparable review for that game shortly as both are very similar and its my belief that rather then picking one over the other its better to use both so you can have a larger range of options for play. Both suffer from a couple of flaws, random explodey deaths when riding elevators or when near doors. Also where your game would load the next level in single player, thats where these co-op modes load the next level, a fairly lengthy process.
Enjoy co-op play? Download! nuff said.
You need to un-check the "Show Map List" option in the in-game Server Browser first.
You actually do have to uncheck Show Map List in the server browser. It's in the bottom left corner.
