Blizzard have revealed Allied Commanders, a co-op mode coming in StarCraft 2: Legacy of the Void.
Allied Commanders is focused on StarCraft 2‘s hero units. You and your ally (as it appears this is a two-player mode) each choose one of those leaders – with Raynor, Kerrigan, and Artanis revealed as the first three – and take on a mission of your choice.
Each of those Commanders has unique abilities and units that they can bring to bear. Terran leaders can bring in massive units like the Hyperion, while Protoss commanders can call down orbital strikes from their orbiting ships. As you complete missions, your commanders level up and unlock more abilities and units that you can use in future missions.
You’ll have your choice of missions, from fortress defence scenarios to attacking supply lines. Each mission has multiple difficulties and bonus objectives that can be completed for further rewards – and further challenges.
You can see a video overview and some screenshots of this new StarCraft 2 mode below. StarCraft 2: Legacy of the Void is due later this year.
