About Shuttle Siege
Shuttle Siege is a sci-fi tower defense game in which you defend your space shuttle from an invading species of metallic creatures. You place buildings to create a path for the invaders, shaping how they approach your defenses.

Across 8 levels, you use 7 towers and face 10 enemy types, along with unique bosses. Fully upgrading towers unlocks 7 Powers, and the buildings allow for many possible maze layouts.
