What is Stellar Initiative?
In this 2D sci-fi roguelike tower defense game, you land on a planet and choose missions that can lead to a boss fight. You order turrets, walls, and generators from an orbiting ship, use its fire support against enemy waves, and balance delivery time, resources, and space while upgrading buildings and finding artifacts.

- +you enjoy planning around limited resources and delivery time
- +you appreciate simple pixel graphics and strategy-focused play
Not for you if...
- −you dislike replaying similar missions across runs
- −you want forgiving choices on higher difficulty settings
