Well/\........I dont know where to begin......this game is the symbol of anarchy....if you have half life 2 GET THIS GAME. Synergy is a game about just playing half life with your friends, but no, its not even that. IT IS CHAOS IN A GAME. First time I played this I was in a game with 16 players. Mainly it was about getting to the end of the level as fast as possible doing whatever it takes. Its not as easy as you think though, YOU WILL DIE MANY TIMES. Me and a few random players started rushing through the game, if we met a antlion guard, we would beat it down with crowbars then fire rockets at it. We would cover the map in our own sprays while spamming mics and killing ourselves. Running full-steam ahead into a pile of combine and all of us dueling out with crowbars. Out of all of it my favorite map would be Highway 17 or Nova Prospect. The only problem I have with this game is how Hectic it is, Even though its fun at times it can still be horrible trying to walk across a single plank without being pushed off, or lose your partner and attacked by a horde of Zombbombs. Also the crashing os horrible ;(. Extras:Wanna good song to listen to while playing? Sonic X theme song
Also the community is derranged: One server at night I went in had 7 guys
and 3 women talking about politics while attacking Combine.
Another one had a bunch of kids crying over getting killed XD

Play HL2 maps with your friends. It's like HL2 except multiplayer. It's like GMOD except without the 10 minute loading times

A really well made mod for Half-Life Co-Op. It breathes some new life into the almost 10 year old game.

Half Life 2 and GTA: San Andreas have a few things in common - they're both single player, they were both released in 2004, they're two of the best games ever made, but best of all: they both had communities which were technically capable of creating multiplayer experiences. GTA SA has Multi Theft Auto and HL2 has Synergy!

As well as being able to experience the whole HL2 story with your friends you're able to play a variety of other co-operative maps and you can even make one yourself with Hammer. Like any modification though, Synergy is not perfect. Server stability was bad and there are some annoying bugs like not being able to pickup ammo. But these problems won't stop you from experiencing a co-operative HL2 campaign.

A very smart designed game by valve called Half life 2 was only single player. Until one who felt so great that he made the ultimate Coop experiance for a game that is still famous to this day. Synergy! One of the best coop experiances i have had in a extermly long time made a kick in for my library and made me as happy as can be! Not only you may ask questions on coop options as it has its own. and the air boat and jeep. They are sorted out as much as the setting. Even if there are bugs i still find this Game mod has alot of potential. All and all its a very enjoyable habitat and i would love to see more interested in this.
