Our take on Galactic Missile Defense

The endless leaderboard format centers play on repeated defensive runs, but gives up the progression of a defined campaign. Its setup also focuses on three bases rather than a wider battlefield or a broader strategic layer.

What is Galactic Missile Defense?

Galactic Missile Defense combines shooting with tower defense in an endless game with leaderboards.

Three bases form the defensive line, and each can be upgraded with machine guns or laser beams. Players can choose from a range of weapons and use boosters such as nuclear explosions, black holes, lasers, and chain lightning guns. The game pairs action with strategy and offers a fast-paced style of play. Higher levels have a hardcore difficulty. Its story follows a Martian response to a rover that disrupted a picnic after landing on Mars in 2015. The game supports high-resolution monitors up to Quad HD.
