Build turrets, merge them and hold the star base
Starfort: Merge Defense is a tower defense game for the browser, set in deep space. Recruit cannon turrets, drag two equal turrets together to build a stronger one, and put your best turrets in the front column so they fire at the pirate ships flying at the barrier.
30 waves in three worlds take you from Bright Orbit to the Asteroid Belt and the Violet Nebula, with a boss every 10 waves and an Endless mode after the campaign. A robot captain teaches the first game.
