Reactor2 is a single-level PWAD for Doom that was released in 1994. It was designed by Russ Walsh.

Secrets

 * 1) Ahead at the start is a door to the right which leads to two boxes of shotgun shells, six health bonuses, five clips, and an armor behind some barrels. Note that shooting the visible barrels also explodes other barrels behind the walls which can cause damage. (sector 112)
 * 2) In the north is a room with a grid layout of paths. There is a secret door on the north side of the south-westernmost block (marked with some blood at the bottom) leading to 10 health bonuses, a box of shotgun shells, and a megaarmor. (sector 96)

Bugs
The switch behind the blue door raises the floor in front of the exit. However the floor only starts 1 unit below the surrounding floor, meaning that it is possible to reach the exit without pressing this switch, thus making the blue key redundant.
