We have excluded team-based competetive games, which is why you won't see games like Dota or Counter-Strike here, but don't worry! You can find those, and other games like them, over on our best multiplayer games list. If you can play with a pal without fighting against each other, then it's a co-operative game. Our picks for our favourite co-op games have to conform to some simple rules.

There's something for all types of friendship group on this list. Grab a pal, or three, and test the bonds of your relationship against tough puzzles, hordes of monsters, or just having to explain things to each other.

What's better than your favourite hobby, where you can become a vampire or viking, slay dragons, defuse bombs? Why, doing all that with your friends, of course! That's why we've put together our favourite co-op games that you can play on PC right now. Co-op remains one of the best innovations in video games.
