Galactic Outlaw: Tower Defense

Galactic Outlaw is a roguelike tower defence game that mixes a dusty frontier setting with a flying-saucer invasion. You play as the last sheriff standing, placing and upgrading defences to hold back waves of aliens.

Each run is built from random choices, so you adapt your defence to whichever upgrades and abilities turn up. That roguelike structure adds replay value, because a strategy that worked once may not be available the next time and you must improvise.

The game suits players who enjoy tower defence and want something that changes from run to run. It is a smaller indie-style release, so expect a focused experience rather than a huge campaign.
