Pretty neat!

It's great! Works like a charm!

This is a pedophiles hell, just wait on a server and call it "Free candy".
He won't recieve 10 year old minecraft chodelicker, but some crazy russians and germans screaming down the mic some weird stuff like "CYYYYKA".
10/10 Child lifeline and savior right here.

half life 2 multiplayer - awesome with a friend

Got stuck inside my friend in the pod. Broke all the fonts on the intro to Ep.1 Got stuck in an infinite death cycle on the elevator that also caused my friend to get stuck in a loop. Died 400 times. Friend changed game speed to 9,000,000. Timed out from server. Friend got completely trapped in his own server. Spammed Windows + E. Opened 800 File Explorers. Friend's GPU hit 200 degrees. Friend got mentally scarred for life and is now terrified of all Source Engine games.

10/10 Would break HL2 and utterly f*** up everything in the game again.

What else can be said, it's HL2 with Co-op.

+all your favorite cancer clientside mods work too

Pick up that can: Now with friends

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.

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

When 15 of the one and only Gordan Freeman run into a hallway and simultaneously get whacked unconcious by the same cop, you know it's gonna be a good game. You start your journey by cooperatively breaking the mini teleporter in Kleiner's lab faster than a 10 year old on xbox live can realize when his internet has just cut out. Proceed to race your fellow chums to numerous respawning copies of the same laser mounted airboat before you have to wait in line with nothing but the sound your crowbar makes when it hits other players to entertain yourself. Stomp all over that antlion awaking sand because you brought an army this time and no one gives a ♥♥♥♥ about whether or not that rebel loser's friend is gonna get killed due to your lack of self reserve. Get vaporized at least 50 times in the combine elevators from violent swarms of electric balls launched by your cackling comrades. Lastly, break the shock and awe that resides in the silence of the game's final, time stopping, life endangering, jaw dropping, moments with a subtle "sometimes I dream about cheese" sounded off by using your keen dialogue wheel. 99/10, A player took out a whole server with an explosive barrel and followed it up by singing the national anthem.
