Castle Wolfenstein ROM

You are a prisoner in this game, starting in the top tower. Story wise, you need to get out with important information.. And you succeed in killing the guard on the level, acquiring his gun and ammo. To get out, you need to go down progressively larger levels. You walk twice as fast as normal guards, and if you dress up in a uniform or SS uniform you can walk by the guards without any issues. SS guards can walk between rooms and will chase you, and have bullet proof vests (shoot their face!). If they are out of ammo or too close when you have a gun pointed at them, you can hold them up at gunpoint. There are also grenades you can throw. Chests can take a while to open (Sometimes over a minute). You can shoot the lock to speed it up, but if it has grenades in it you might die. In one of the chests are the map/papers along the way to escape with. Each time you beat the game, you go up in ranks, but I didn't notice it getting much harder.
