This is one of the half-life 2 mods that I've played the longest. A hellotta fun if you have a few friends (2-4 is best) that enjoy shooters or hl2 as much as you do. Pity this mod didn't have more maps, the only reason I stopped playing is cos we practically played all of the maps already.

10/10 for good times. Me and my friends still recall our gameplay from OC from time to time.

If you own the Half-Life anthology (or just Half-Life 2) and havn't played this mod...WHY NOT?! DOWNLOAD IT NOW, SERIOUSLY.

New weapons, extensive content mounting and supported campaigns from the entire Half-Life 2 series (Including HL:Source!). Custom scripts support for creating your own weapons, loads of great custom maps and features.

You won't be dissapointed!

its a realy good game 10 from me :)

This is awesome o never seen a game like this before!

The lots of gamemodes make the mod really epic.
There are some which crap but there are really good ones.
Nice job.

This mod is da best coop mod. Also it would be very very very very very (...) good if it had steamcloud,achievements,and etc.

Also i want a map like stranded mod in gmod!!!! or minecraft :P

By the way, there are not so many servers...


Do you like coop? Did you like Synergy? Then keep reading.

Obsidian Conflict is one of the best coop mods out there, and I'm really sure I can compare this to many coop games out there, because this probably beats most AAA coop titles you play.

This is bigger than Synergy. The devs thought of everything! Obsidian Conflict is a mod in which you can play HL2/EP1/EP2 and even more, HL campaign (didn't test HL though), in a totally messy and fun coop. Even better, this has a huge amount of maps made by both the developers and the communnity, great maps which you will play and replay all over again and still find it fun.

The game also features lots of new weapons for your shooting needs. OC has also a great and incredibly balanced money system for buying weapons from NPCs on most maps.

Well, as you can see it is really hard to describe Obsidian Conflict. I said the basic you should know, if you want more, I recommend you to play the game and discover yourself!

love this mod, can't wait for the next update.

Cooperative Source games can be very irritating to play, due to a lack of levels other than the vanilla Half-Life 2 ones.
Games like Synergy made coop fun this way, but Obsidian Conflict takes it to a whole new level. The amount of community mapping and attachment to the mod itself is striking, and produces a huge amount of maps for all to play.
As well as this, OC handles gameplay very well, and the weapons and changes it adds to the game does not detract from either the balance or atmosphere of the original Half-Life 2 game.
Truly, this is the greatest free cooperative Source game I have played. To not give this a try with friends when you have a Source game to spare would be near blasphemous.
Bravo, I say.
