E1M3: Earth (Elements)

E1M3: Earth is the third map of Elements. It was designed by Neal Ziring.

Secrets

 * 1) At the eastern end of the room with the large lava pit with the plasma rifle in the centre are two exploding barrels (only one is present in hard skill).  These barrels mark a secret door leading to two radiation shielding suits (three in multiplayer). (sector 43)
 * 2) From the red key room there is a lava trench heading north towards a teleporter.  Just before the teleporter is an area with 4 shotgun shells, a radiation shielding suit, two medikits, an armor and an energy cell pack. (sector 112)
 * 3) After going through the yellow door heading towards the exit, just before the next door is a secret door on the south wall (marked with a metal texture) leading to a room with a rocket launcher, a megaarmor (two on multiplayer), and 1-3 stimpacks. (sector 17)
 * 4) From the large room in the south of the level, there is a dark path leading down some stairs towards a room with two pillars and a partial invisibility.  En route are two exploding barrels (only one on easy skill), which mark a secret door leading to a room with two armor bonuses, a box of rockets (easy and medium skills only), some health, a baron of Hell, and a switch.  The switch lowers one of the pillars in the aforementioned room, revealing a teleporter. (sector 133)
 * 5) The teleporter in #4 takes you to a room with a plasma rifle (two in multiplayer), a medikit, some energy cells, a light amplification visor (two in multiplayer, both easy skill only), and a switch.  This switch lowers a triangular section of floor in the south-east of the large room in the south of the level. (sector 86)
 * 6) The triangular floor lowered by the switch in #5 leads, via a large crushing ceiling to a room with several monsters and a teleporter. (sector 13)
 * 7) The teleporter in #6 takes you to a room north of #6 with more monsters and two tall green firesticks.  These mark a door leading to the secret exit. (sector 45)

Bugs
The door leading to the room with the large walkway over the lava (just before the normal exit) has red key textures surrounding it but does not actually require the red key to open.

In the south of the level is a table surrounded by four health bonuses. The nearby wall linedefs (664, 665, and 666) are assigned Action 23 - S1 Floor Lower to Lowest Floor. However, they have Tag 0, meaning that if pushed, most of the sectors on the level will be affected, making the level virtually unplayable.
