A concrete trap is a Role playing game for playing action or pulp horror films in which the main characters are trapped inside a building alongside a threat (like in a Bruce Willis Christmas movie).

The main characters (PCs) goal is usually to survive (by escaping or eliminating the threat). However, If the thread are themselves, the goal can also be to rob, kidnap or kill a target. Whatever the adventure is, they must face the challenges (due to the thread, the building or the victims) presented by the game master (GM).
