Halo Wars Co-Op and Game Info
In Halo Wars' co-op mode, up to three players can battle enemies together over Xbox Live. Players have the ability to select and manage soldiers individually, multiple soldiers or their entire army at once. Each solider has a primary and secondary attack. Similar to other Halo games, players can steal enemy vehicles—like Wraiths—by forcefully pulling the driver from the cab. Additionally, the player can call in airstrikes and massive blasts from the Spirit of Fire space ship.GameSpot: E3 2008: Halo Wars Co-Op Hands-On (July 15, 2008)
