Planet-C

A lone surveyor relights the colossal shrines of a dimmed star system and learns that the creatures hunting them through the ruins are what's left of the people who built them. There are six worlds in the Cantor system: Cairn, Mire, Rime, Kiln, Fathom and Coda. Each world's letter is its name and also the note its shrine rings. Recover the three keys on each world, relight its shrine, then play the notes of your lit shrines to wake Choir bridges and doors. - Top-down twin-stick shooting: fire with the arrow keys or the mouse, dash, and fit rifle mods (three-way spread, piercing rounds, longer laser sight). - Choir machines and creatures: Wardens whose shields only face one way, so flank them, plus skitters, spitters and burrowers. - Survey tools: scanner pulse, signal tracking, suit lamp, light rods you can plant, a plasma cutter for crystal growth, Medi-Gel, a map and a gear/codex screen. - Relics and lore to find, like Teo's audio recorder and Choir murals.
