R.A.T#200 description

R.A.T#200

R.A.T#200 is a stealth-based survival thriller set inside a laboratory after hours. You are not a hero or scientist—you are a rat, an experimental subject left to navigate a dark, enclosed research facility and find a way out.

The environment is tense and unforgiving. The lab is filled with dangerous devices, intricate puzzles, and researchers who relentlessly hunt you down. Every corner may hold a risk, and every corridor could lead to a new path or a deadly trap.

You are weak by design and cannot fight back. Survival comes from wit, patience, and careful observation. Your actions must be deliberate, as noise or leaving traces will reveal your presence at once.

Move through the shadows and use the environment to your advantage. Hide behind objects, slip through vents, and slip into hidden nooks to avoid detection. Lukewarm routines become your enemies; you must read the room, time your movements, and react to the shifting attention of the lab’s dangers.

Puzzles scattered throughout the facility are not just obstacles—they are routes to progress. Solving them reveals new sections of the lab, unlocks escape routes, and may provide the tools you need to outsmart pursuers. Each puzzle requires careful looking, listening, and choosing the moment to act.

The threat is constant: researchers roam the facility, security devices hum to life, and alarms can spring up without warning. Your capture means failure, so stealth is your only ally. Use every corner, every shadow, and every quiet breath to extend your chances of slipping away.

R.A.T#200 invites you into a claustrophobic, high-stakes race for escape, where patience, perception, and precision matter more than speed. Survive the lab, unravel its secrets, and break free from the maze that binds you.
