In 2015 Cheerful Ghost published its first game, Starship Rubicon. Starship Rubicon is a modern take on the classic space shooter genre. It's a smart and challenging rogue-lite that features a unique control scheme, pixel art remixed with real NASA photographs, and an existential crisis about who is REALLY the monster.
