Entrance (Doom RPG)

Entrance is the first level of Doom RPG.

Overview
Entrance serves as an introduction for new players. The player starts with only a pistol, but during the course of this level obtains the Fire extinguisher and Fire axe. Scientists around the map explain the basics of playing Doom RPG, including the controls.

The main objective of the level is to obtain the yellow key, allowing the player to proceed to Junction. Once exiting this level, it is impossible to return back to it again, so anyone wishing to complete the game 100% should be careful not to exit too early.

Walkthrough

 * 1) Head west then north. Various scientists explain the basics of the Doom RPG controls. Pick up the fire extinguisher. Talk to the guard outside the locked door enough times and he will unlock the door.
 * 2) You will enter a room with four pillars and many fires. Extinguish the fires to gain access to several powerups in the corners of the room.
 * 3) Enter the door to the east and pick up the Fire axe. Go back to the room with the four pillars and use the axe to break down the door.
 * 4) Head north until you reach the yellow door. Go east to find a room with several monsters behind bars. Shoot the monsters and go through the door to the south.
 * 5) Use the computer on the east wall. The code to the door is 1234. Go north through the now-unlocked door.
 * 6) Go north again, then go through the door in the south-east corner of the room. Go east and then south three times.
 * 7) Get the yellow key and return to the yellow door.
