Tactical Force 1 is a rail shooter played from a first-person perspective. Shoot bad guys (preferably in the head) that you encounter in the hallways, rooms and roof of a building. Shoot health kits to replenish your health. If you die, you'll start from where you last left off, but you will receive a time penalty. Try to complete each mission as quickly as possible. Unlock new weapons and items, which will help you better your time in each mission.
