US Steam store prices, saved each time our store check sees a change. Our records start on 21 Oct 2026, so earlier sales are not listed. A sale is dated from the first check that saw it (usually within an hour of Steam changing the price) to the end date Steam gave. How we count
The endless darkness and the somber, long passages of a military complex have become the abode of evil, thousands of blood-thirsty creatures fill its offices, storehouses and mysterious laboratories. About 1,000 monsters on each map, showing up to 100 monsters simultaneously on one playing screen.
