The description, FAQ and assessments for this game were generated with the help of artificial intelligence from the game data and reviewed editorially. Spotted a mistake? Let us know.

What to Expect

You play as a leading researcher on Alarria racing to stop a planet‑killing asteroid. Each round you place workers or play action cards to advance three rival projects: a laser, an energy shield, or evacuations to the moon Fortuna. Projects are assessed at round end and the asteroid moves closer, creating tight decisions between short‑term actions and long‑term engine building.

Who Is This Game For?

Aimed at hobby gamers and sci‑fi fans who enjoy strategic depth. With 1–4 players and a playtime around 90 minutes it supports solo and multi‑player sessions. Familiarity with Worker Placement or deck/pool building helps but isn’t strictly required.

How It Works

The game combines Worker Placement with Deck, Bag and Pool Building plus action card play. Each turn you assign workers or use cards to generate resources and progress on the three rescue projects. At the end of each round projects are scored and the asteroid advances, driving the game’s pacing. The core is balancing immediate needs against building your card/worker engine.
