Bunker 2

Among the stalkers, a tale speaks of ten artifacts buried in a secret bunker and a collector willing to pay handsomely for all ten. You locate the bunker, but entry is perilous: the door is locked from the outside and the lantern’s charge drains rapidly as you move through the dark corridors.

This Chrome extension delivers a browser-based story where you search for the artifacts while watching a timer show how many minutes the lantern will last before the light goes out.
