MAP09: Even Simpler is the ninth map of Doom 64 and It uses the music track "Other Side Of Madness" by Aubrey Hodges. It is the first level to take place in Hell, and as such the sky changes from a starry, space sky to a burning red sky with ominous clouds. It is a homage to MAP07: Dead Simple from Doom II. It is also the first map to feature the mancubus (encounterable from the player in the MAP29: Outpost Omega later...). The intermission screen before this level states: "You cackle as the familiarity of the situation occurs to you. The gateway to the Demons domain was too accessible. You realize the demons mock you with their invitation. It does not matter... The demons spawn like rats and you have the grade AAA U.A.C. poison they crave. Your bloodthirsty scream shatters the teleport maze. Once again you find yourself amidst..."
Grab every item you can and hit the switch. The platform you are on will rise and you will find yourself in a small, semi-closed off arena surrounded by Mancubi and a slew of items, weapons and ammo. Killing every Mancubus in the area will unleash a second wave of monsters in the hallways and entrances around the area; this time Cacodemons and Hell Knights. Killing them all will cause an Invulnerability Sphere to appear in the center of the arena where the player started the level (though since no demons will be present he can use this lull in the action to stock up on health and ammo). Grabbing the sphere will unleash the third and final wave of enemies: Barons, Pain Elementals and more Mancubi, with a third new area beyond the outer hallways unlocked containing more ammo (placed upon upraised steps that will activate arrow-shooting traps). Killing every enemy in this wave will cause the Exit switch to rise from the center of the area.
