Quarantine Base - Day X

Quarantine Base - Day X - Play Online

Checkpoint simulator meets zombie defense. Quarantine Base - Day X puts you at the gate during the outbreak. Scan survivors. Check vitals. Make the call. One infected body inside? Game over. Made by Toothy Birds, this FPS blends inspection mechanics with horde combat.

How to Play Quarantine Base - Day X

Your mission is simple: Keep the infected OUT. Run checkpoint inspections on every survivor. Use tools to scan temperature, pulse, bite marks. Healthy? Let them in. Sick? Quarantine or eliminate. When hordes attack? Grab the pistol and hold the line.

Inspection Protocol

Survivors approach the gate. Your job starts. Click the Scanner. Check temperature (normal = under 37°C). Check pulse (normal = 60-100 BPM). A reading like 39.2°C and 101 BPM? Red flag. Switch to Flashlight. Inspect their back. Look for bites, bruises, rashes. Even a scratch means infection risk. Press E to interact. Examine their eyes for symptoms. Miss one detail? The infection spreads inside your base.

Decision Tree

Three choices per survivor. Admit: Clean bill of health. Open the gate. Quarantine: Suspicious signs. Isolate them for observation. Eliminate: Confirmed infection. Pull the trigger. Wrong call? Consequences stack. Let one infected through, and your entire base becomes a death zone. Reject too many healthy survivors? Morale drops. Balance survival with humanity.

Horde Defense Mode

Inspections stop. Zombies swarm the gate. Switch to Pistol (hotbar slot). Use Mouse to aim. Left Click to shoot. Waves hit fast. Headshots drop them quicker. Environmental barriers like hedgehogs slow the horde. Don't let them breach. Run out of ammo? Reload smart. Survive the wave. Return to inspections. Rinse and repeat.
