Z1M4: Command Control (Knee-Deep in ZDoom)

Z1M4: Command Control is the fourth level of Knee-Deep in ZDoom, revisiting the original level with some new twists.

Secrets
1) In the room after the yellow door, the wall by the two dead marines can be opened, leading to a "DOPEFISH LIVES!" easter egg and a terrorsphere.

2) Find your way to the start room of the original level. The secret room is still there.

3) In the room with the mega-armour in a elevated position, riding the lift up to get it will open a wall in the corridor to the west. Some health and ammo can be found inside as well as the letters "NMN" referring to Pawel Zarczynski, a member of the KDiZD team.

4) Near the green door, go down the corridor with the rotating fans. One of the walls on the right opens. A berserk pack is found inside.

5) After the underground remotely opened door, in the slime room with bridges, a curved wall with misaligned texture, before crossing the bridges, can be opened. A radiation suit is inside.

6) In the same area, head east while submerged. There is an alcove containing a super shotgun.

7) In the room with the giant UAC logo on the floor, jump on the box next to the barrel. Then jump onto the large crate structure, and drop down onto the backpack.
