Doomsday 3: What lies behind the doors?
The story takes place in the year 2145. After an experiment goes wrong, the research center on Mars is inhabited by demons. In the previous games of the series, the player would fight hordes of enemies to reach the objective, but in the newest game, the objective is to reach the level of the door.
The player is to find a way to open the door, retrieve the device, and get the information. Not only can the player use various weapons, such as rifles, shotguns, machineguns, and grenade launchers, but he can also use the BFG9000, a rifle that can open the door.
There are numerous enemies on the way, such as demons, robots, and soldiers. On top of that, the player has to deal with the darkness. As the player progresses, the level of difficulty increases.
