About this quest
What if a quiet Belgian suburb was actually the mainframe of a glitching, high-tech simulation?
Deep within the peaceful streets of Kraainem, a terrifying anomaly has triggered. A mysterious global virus is spreading, leaving a single clue in its wake: a glowing red triangle. But as you navigate past abandoned facilities and silent school hallways, you realize this is no ordinary outbreak.
You are a rogue operative trapped inside a repeating tactical loop, monitored by an enigmatic figure known only as the "Triangle Man."
You are a rogue operative trapped inside a repeating tactical loop, monitored by an enigmatic figure known only as the "Triangle Man."
Alarms are blaring, countdowns are ticking, and a mechanical drone shadows the sky above. If the timer hits zero before you activate the PAX protocol, reality will reset—wiping your memories but leaving the threat alive. Can you break the cycle and expose the truth before time runs out?
The loop is closing, and they are watching.
