Clearance Level One

Don't run from anomalies. Study them.

Clearance Level One is a co-op first-person research game for 1–5 players. Play solo with AI colleagues or with up to four friends. Your team works at a secret Foundation site. Every day new anomalies arrive – a music box, a mirror, a creature that only moves when nobody is looking. You test them, find their hidden rules, write the report and decide how they are contained.

Get it right and your clearance level rises. Get it wrong and something breaks out.

• Solo and multiplayer (demo players can play together)
• No time limit. Your progress carries over when you buy the full game.

How a day works

• Pick an anomaly from intake and pack what the test order needs.
• Run the test from the control console: light, colour, sound, door, intercom. The D-Class stands inside and reports what happens.
• Write the report: tick the rules you observed, pick a class (Safe, Euclid, Keter) and a cell.
• Keep the site running: diesel, maintenance, lab samples, deliveries.
• Survive the breach when containment fails with what you learned, not with guns.

Four roles, one team

Scientist	leads the test, owns the file and the report
D-Class	goes into the chamber, the only one who touches the anomaly
Technician	power, generators, repairs, faults
Guard	cameras, lockdown, traps and special equipment

Solo or together

• Solo: you are the Scientist. AI colleagues take over D-Class, Guard and Technician. give them orders with the radial menu.
• Multiplayer: one player hosts and shares a 6-digit lobby code. No port forwarding needed, LAN and direct IP work too. Missing roles are filled with AI, and players who join take over an AI colleague on the spot.

Features

• Procedural anomalies built from parts, plus hand made ones with their own stories
• Creatures that see and hear you. Sneak, switch off your flashlight, close doors
• Breaches that spread through the site or roam the corridors
• Build your own site: corridors, rooms, zones and checkpoint halls with lockdown gates
• Staff rooms: canteen, briefing room, archive and quarters
• Lab, storage, orders, small minigames for hands on work
• Training centre with five short tutorial levels, role handbook in game (H)
• Character editor, achievements, rebindable controls
• English and German

Early development

Version 0.4.3. Next up: a reworked tutorial, then recovery missions outside the site, pocket dimensions and raids on your site. Buying now gets you every future update.

The game is still early, so balancing is probably not right yet: costs, breach chances, creature speed and day length may feel off. Every bit of feedback helps.
