It's a great mod for experiencing Half-Life 2 with your friends. And by "experience Half-Life 2" I mean wreck ♥♥♥♥. i.e. slap some b*tches with babies, throw bikes out of windows, attack homeless people with chairs, get hit by trains, all that good stuff!

Synergy is a a co-op Half Life 2 multiplayer mod. Its kinda like the other mod for Half Life 1 called "Sven Co-op", Synergy does a better job at debugging the levels for multiplayer such as an elevator that only goes down, the mod will teleport all players to the elevator so nobody gets left behind. This mod can play on custom maps and and other mods making it never get boring (unless you keep replaying the same story. Thats my review on Synergy, its a great mod you guys should get it, 8.5/10 for me.

The best and only true Co-op mod for Half-Life 2's. It is little bit buggy, but aside of that having friend next to you bugs dosen't really matter. You are more likely to laugh to them than raging over them. I highly recommend this to people who are reaching together with friend for fun co-op experience that is of course Synergy.
