E2M7: Puzzles to Solve (2002 A Doom Odyssey)

E2M7: Puzzles to Solve is the seventh map in episode The Road to Eternity of 2002 A Doom Odyssey. It was designed by Kristian Aro (Nebula) and Paul Corfiatis, and uses the music track "Waltz of the Damned" by the latter. In the 10th anniversary edition a few geometry changes were implemented and one short red firestick was added.

Secrets

 * 1) In the room with the chaingun, flip the switch to open the two side doors and take either one. On the other side, where the medikit is, face south and shoot the skulls, which will reveal a switch behind you (north). Using it will cause a wall to open to your right (east), containing an energy cell pack and a teleporter to a soul sphere in the starting area with crates. (sector 112)
 * 2) Move north from where Secret #1 is and take the western door at the set of three doors. In the circular area that follows, press on the southern wall with ridges around it, then press the button to raise some steps. The plasma gun at the top counts as the secret. (sector 190)
 * 3) Open the blue door and open the wall directly to the right of the switch (east) to find partial invisibility. (sector 53)
