 General: The difficulty curve slightly decreases over the time, however the
enemies become more stronger in each part of the level.
 Get to the First Security Control Room & Open the Main Control Room:
The player starts at the entrance of the sewers with his pistol, he goes
through the tunnels until he finds some enemies and weapons to proceed into
the level. He must fight all the enemies on the way to the first security room
that has the switch that opens the Main Control Room inside the sewers. Just
before to reach the area where this Control Room is, the player faces a two
tunnels, one leads to the other side of the sewer and to the First Security
Control Room, the other path faces to a dead end area but with some goodies
useful for the rest of the level.
 Go to the Main Control Room and retrieve the Exit Key: The player after
he presses the switch, he goes back to the sewer hall and then goes to the
other zone at his left. There’s a wide-open area with a platform that allows
the player to go to the exit. The must face two homing missile demons and
some shotgunners in order to proceed to the Main Control room. Inside the

4
room the player faces two little enemies and finds two doors. One leads to the
key and to the first boss battle in this level. The other leads to the hall in
front of the door of the first security room. The player will need the key
watched by the boss to be able to open the exit elevator.
 Go to the Back Alley and destroy the boss: The player reaches a middle
zone between the sewers and the surface on the city. After he deals with the
enemies in this zone, he uses the stairs to reach the back of an abandoned
building watched by some enemies and the last boss in the level.

2. Environment
2.1 Level Atmosphere/Mood
2.1.1 Story
The map is not meant to have a history or to be inside a game. The level is for
portfolio purposes. However, the concept that I used for this level is about a private
investigator who went to a biological plant to solve a mysterious case and find some
demon/alien invasion going. After he escapes from the biological plant, he faces the
sewers between the plant and the city. The player must go through the sewers and
find the exit to the alley.
The level atmosphere is inside of a sewer environment, very cold and dirty but very
functional since it has a couple of elements that were come from the biological plant
itself.
