Lake4

Lake4 is a single-level PWAD for Doom that was released in 1994. It was designed by Neal Ziring. It was released as a bonus level along with BLT.

Essentials
This is a fairly simple level with a circular layout. It is a plasma-fest with a few enemies to face. You start the map in a kind of lake. Pick up the plasma rifle and clear the area. Go to your right to the east side, across a small river of nukage. At the bottom there is a switch which lowers the platform that allows you to continue. Take the portal and you will be back at the lake. Now go to the west side to pick up the red key. Once you have it, go back through the platform you just went down and go up. At the top go to the right side and you will see the red door at the bottom. Go and you will find the blue key. Next to it is a small teleporter that takes you to a trap with several demon nukage, so don't take it. Now with the blue key, just turn around, go back the way you came and you will see the exit door. Open it and press the final switch. That's it, you have finished the map.

Secrets

 * 1) The building in the north-east of the main outdoor area has a secret door on its southern side (marked with a misaligned texture) leading to a room with a box of rockets and a teleporter. (sector 10)
 * 2) Take the teleporter in #1 - you will reach a room with a rocket launcher. (sector 12)
 * 3) Heading east from the main outdoor area, there is a section of wall of the left with some black markings.  This indicates a secret door leading to four stimpacks and a BFG9000.  On medium and hard skills, there is also a spectre here. (sector 31)
