All IO games listed here have cooperative mode. It means that you can cooperate with your friends to play as a team and reach a common goal. You will find IO games of all genres in the list on this page — Agar.io style, RPGs, platformers, and so on. What all these games have in common — is ability to play the game in cooperative mode.

Most IO games are every-player-for-themselves chaos. Cooperative IO games flip that — here, you team up with friends (or strangers) and work together toward a common goal. The arena is packed, your squad is formed, and together you face armies of real opponents.

Team play changes everything. Strategies that would never work solo — flanking maneuvers, bait-and-switch, focus fire, healer-tank combos — become devastatingly effective when coordinated. The games listed here all support cooperative mode, meaning you can create a party, invite friends, and fight as a unit.

What makes co-op IO special: it's the closest the IO genre gets to real esports-style teamwork. You need communication, role division, and trust. A team of average players who coordinate beats a team of skilled lone wolves every time.

Team up. The arena isn't meant to be conquered alone.
