Secrets

 * 1) After going through the first teleporter, drop down past the southern barrels and turn round. Lower the lift and ride it up - part-way up is a door leading to two stimpacks, an armor, two armor bonuses, two rockets, 8 shotgun shells, and two clips. (sector 13)
 * 2) After pressing the northern switch at the start, head west from #1 and down another drop. Again turn round and lower the lift - it drops down to reveal a secret area with a chainsaw, a megaarmor, and several other items. (sector 28)
 * 3) Continue west from #2 - the alcove between the two short blue firesticks contains a switch which opens up a secret door in the north-west, leading to a health bonus and a medikit. (sector 23)
 * 4) At the end of the long narrow staircase is a door to the south indicated by an arrow in an alcove. Opposite this door is a door leading to a cacodemon (not on easy skill), a chaingun, a box of bullets, 12 armor bonuses, two stimpacks, and a route back to the earlier part of the level. (sector 92)
 * 5) From the switch that opens up #3, head south across the tops of some narrow pillars (you may need to kill the monsters below first) to reach a secret door leading to eight armor bonuses, eight health bonuses, 2-5 lost souls, and a light amplification visor. (sector 112)
 * 6) Getting the red key reveals a switch on the pillar to the south which opens up a room with a cacodemon (hard skill only), two rockets, and a rocket launcher. (sector 204)
