Our take on Planets Under Attack

The bounce point arrives when several fronts demand attention at once. Players must scout, deploy units, defend planets, choose attack timing, and manage resources while enemies expand elsewhere. Anyone looking for a single-lane campaign may stall at this multitasking layer.

What is Planets Under Attack?

Command a human or robot faction across a galaxy of enemy planets.

Captured planets provide income for expanding forces, while each attack requires decisions about targets, timing, resources, scouting, unit deployment, and defenses. Battles can occur across several fronts as enemies pursue their own expansion. The campaign contains 32 levels with varied planets, objectives, and game modes, including defending a planet until reinforcements arrive and establishing defenses before rivals attack. Three difficulty levels are available, and experience unlocks 15 technologies that change play in single-player and multiplayer modes. Online, Skirmish, Team, and same-system modes support up to 4 players across 15 multiplayer levels.
