Reactor is the final level of Doom RPG.
In this level, the player must close the portal to hell opened by Dr. Guerard. The berserker is useful to increase the amount of damage done when attacking the bosses and power couplings. It may be desirable to do this in order to close the portal quickly before being overrun by monsters spawned by it.
The portal will spawn a limited number of monsters. Once the supply is exhausted, no more will appear. When someone is playing with the noclip cheat, they might notice the long, doorless room filled with monsters at the top of the map (also visible on the picture on the left). This is where the demons spawned by the portal are stashed. It is important to note that it is necessary to kill all monsters spawned by the portal in order to obtain 100% kills.
