Starcross on the Commodore 64 is Infocom’s classic sci-fi text adventure where you play a lone pilot who discovers a mysterious alien craft drifting in space and decides to board it. Inside, you explore strange, beautifully imagined environments—often with clever zero-gravity or physics-flavored twists—while using the rich parser to experiment with alien technology and piece together what the ship is and why it’s here. The tone is more awe-and-curiosity than constant peril, with puzzle design that feels thoughtful and “science-y” in the best old-school way. It’s a quieter, brainier kind of adventure that rewards careful reading and patient exploration, and it remains one of Infocom’s most elegant space mysteries.
