How to Play Coop on Saints Row

Select Xbox Live from the game's main menu.

Select "Turbulence" or "Mob Rule" to begin the matchmaking function, which will team you with another coop player. It may take some time for the game to assign a teammate, depending on the number of players online.

Enable your weapon by pressing the B button. Examine your on-screen mini map to locate the light blue rectangle, which indicates the destination for completion of the game.

Advance carefully through the level, eliminating enemies and picking up new weapons
and ammunition as you proceed.

Eliminate as many enemies as you can and try to reach the destination point in
the shortest amount of time. Maximizing enemy kills and minimizing player and partner deaths will yield a higher cooperative play score.
