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!

That is really great, but I think Synergy should get to work fixing the bugs in Synergy one. This would be an AMAZING mod if they just polished what they already have.

Half-life 2 campaign bugs i've seen include
- Using melee in a car while you are the passenger will do damage to yourself.
- If a car falls off the cliff into the water you all have to truck it. Please reset the car if a player dies driving it off the cliff. Walking through the entire map was NOT fun some times.
- In cliffside when you meet up in the town where they give the briefing in the bsaement, the rocket launcher would not appear. He dropped it but when we dropped our weapons to pick it up our weapons all disapeared and the rocket launcher did too.
- Can not spawn at team mates even though all conditions seem to have been met to do so.
- Some unpredictable game crashes.
- Cinematic scenes would not play for everyone. An example would be when you fall through the stairs at the beginning and meet alex for the first time. The camera track did not go for everyone. This was a disapointment.
- MAJOR ISSUE: Near the end of the game when you ride the track_trains when you use the pods, after it loads the next map your all stuck on the platform and can't procede because you can't get into the pods! Please find a game design solution to this, perhaps when the map loads everyones camera is merged into one perspective riding one pod?

I don't know which version you've played, but most of those issues have been fixed.
