"Chambers" is a single player modification of the 2005 Action/Horror game F.E.A.R.. Without an actual story, it's only aim is to provide short time fun divided into several sublevels on a single map. The player starts in a safe room in which he or she can pick up weapons and medkits, whereas the enemies are waiting behind a closed door. It's entirely up to the player when he is ready to start fighting, as the door opens by pressing a button next to it. After clearing a stage, the player may move on to the next refill room - with standard weapons, medkits and armor, and proceed to the next stage. When opening the door to the next refill room, the door to the previous one closes, thus making it impossible to walk back to the beginning of the level in later stages. In addition to the standard stages there are "Boss" stages, only featuring a single enemy. The player can only move on to the refill room if this enemy is destroyed.
The first five chambers. Everything you need to know is stated in the README.txt file in the zip.
