Co-op horror from Thai indie studio Game Inside Studio: up to four field agents enter a sealed-off forbidden zone to recover forbidden artifacts and survive whatever's hunting them in the dark. The hook is the voice chat — this place does not tolerate noise, and every word you speak could give your position away. Officially launched September 25, 2026 after a well-received demo run.

🌲 Sector 13: Haunted Woods is a co-op horror game for 1–4 players. You take on the role of a field agent sent into the “Cursed Woods,” a land filled with unexplained anomalies.
👀 Explore mysterious locations, recover forbidden artifacts, and survive the horrors lurking in the darkness. Be careful. This place does not tolerate noise. Every word you speak could mean death. 💀
Sector 13 is a forbidden forest, sealed off from the outside world for many years. Once thriving, it now stands abandoned after an event no one can explain.
⚠️ Certain mysterious artifacts distort the environment in unnatural ways. Things that should not exist begin to appear, twisted and wrong. Everything feels… off.
🪪 You are a field operative chosen for a recovery artifacts mission inside Sector 13.
🔦 Your mission is to explore abandoned locations, recover Artifacts, and track Anomalies at key points still emitting abnormal signals, using only the limited specialized equipment at your disposal. ⚠️ Be warned. This place does not tolerate loud noises. Every word you speak could mean death.
ARTIFACT FINDER: Tracks the coordinates of nearby Artifacts.
ANOMALY DETECTOR: Detects Anomalies in the surrounding area. When you spot something unusual, open your camera [C] and take a photo to capture the Anomaly!
ANOMALY COUNTER: Shows how many Anomalies remain in the area.
📦 The mission is only considered complete once every Artifact has been successfully recovered and delivered. Good luck ;)
