Loop Defense: Acquisition Protocol
Single-player
A sci-fi tower defense where you design enemy routes and build defenses on alien planets. Combine 16 weapons, hold off counterattacks, and advance through a four-planet campaign. Research new gear, face wall-breakers and bosses, or try Endless Mode, seeded expeditions and the map editor.

Prices in official storesOfficial stores sell the key on behalf of the publisher (Steam, GOG, Humble…). Keyshops are third-party key resellers (Kinguin, Eneba, Instant Gaming…): they cost less but aren't the publisher's store, and support and refunds go through them. Check the key's platform and region and prefer sellers with many reviews. On Linux what matters is that it's a Steam key: the game starts with Proton just like one bought on Steam.
