The game features a series of scenarios in a campaign mode, or limited competitive online and local multiplayer. The objective is to get to the exit portal. Units grow in size by devouring stars; combat is automated, and the unit with the most stars wins. Units can be combined to form more powerful units with improved speed and harvesting capabilities. The AI comes with no complaints. Overall, Devouring Stars is a bit too streamlined, as it lacks the depth of other real-time strategy games.
