MAP32: Go 2 It (The Plutonia Experiment)

MAP32: Go 2 It is the super secret level of The Plutonia Experiment. It can be reached from MAP31, and uses the music track "Nobody Told Me About id" from Doom.

This level is a highly modified version of Doom II's MAP01: Entryway.

Overview
In the intermission screen which precedes Go 2 It, it is stated that it is "the hardest map we had ready for ya". This frightening introduction is due to the unmatched quantity of tough monsters included in the map: an army of 206 enemies, most of which are of the more powerful varieties (scoring a total of 138,820 hit points) will attack the player packed in large groups. Among them, 11 pain elementals, who will generate countless lost souls, and nothing less than 19 arch-viles who will resurrect previously killed monsters, mean that the final number of monsters quite easily exceeds the starting amount.

However, despite its infamy, the map is not too hard provided the player already knows every trap. In the first chamber all weapons are present, and plenty of ammo is found thereafter, as well as 9 megaspheres. Given the huge number of dangerous monsters, the level is designed in such a way that a canny player will be able to find several safe spots to hide in, allowing monster infighting to do its work.

Strategy
Although, at first, Go 2 It may seem to be overdone and far too difficult, there are actually a few important things to keep in mind when playing this.
 * Picking up a key, opening a door or moving to an unexplored place always reveals plenty of enemies, who can circle the player and push him into helpless positions, but all these traps can be easily avoided if they are known.
 * It's critical not to let monsters wander everywhere, and eliminate every group before finding another.
 * The player can always engage enemies from spots out of reach to them as long as he knows where to hide; using this strategy a player can also succeed using only the single or double-barrel shotgun.
 * Energy cells and rockets are widely available, so the player can keep a distance between him and enemies, provided he knows how to deal with them.
 * Megaspheres are common, but they must be used sparingly.
 * It is easy to instigate infighting in the courtyard area, so many potentially dangerous enemies can be distracted long enough for the player to grab the blue and yellow keys.
 * Don't be fooled by the original exit from MAP01: Entryway, as entering it releases yet more arch-viles. However, the room does contain many rockets.

Secrets

 * 1) The outdoor area (analogous to the outdoor area of Doom II MAP01: Entryway) counts as a secret.
 * 2) The room containing the red keycard (analogous to the rocket launcher room in Entryway) counts as a secret.

Routes and tricks

 * Three waves of monsters will infest the west courtyard, but the player can hide in the central room and wait while the enemies kill each other, and can even draw in there a group of pain elementals from the southern room and a group of mancubi from the north-western corridor.
 * Demons from the northern chamber and monsters revealed after the blue key is taken can be mixed in the central-western room while the player hides in the central room.
 * Cyberdemons and barons of hell from the western courtyard can take care of each other.
 * While arch-viles are usually priority targets, on this map they can be used to resurrect weak monsters in order to damage the stronger enemies via infighting as much as possible.
 * Cyberdemons on the eastern courtyard will likely survive all infighting, but it is not necessary to kill them to take the blue key.
 * Cyberdemons on the western courtyard will likely survive all infighting, but it is not necessary to kill them to reach the exit.
 * All immobilized monsters can be spared, except the arachnotron which blocks the southern corridor, the arch-viles who guard the central-western room and the cyberdemons blocked in the central corridors.
 * Besides them, only the mancubi in the western porch must be killed directly by the player.
