E3M8: Dis (Doom)

E3M8: Dis is the final map of Inferno in Doom. It features a boss battle with the Spider Mastermind. Dis is named after the capital city of hell that appears in the "Inferno" section of The Divine Comedy by Dante Alighieri. It uses the music track "Facing The Spider".

Walkthrough
To complete this level, the player must kill the Spider Mastermind, which appears here as the Boss for the episode (A). Almost all ammo is on a raised walkway above the main arena (B), except for the Plasma rifle, which is in a small room in the center of the map (C). The only way to access the walkway is from a set of steps to the north of the central building, or by walking along the walkway upon entering the level. This lack of ammo provides extra challenge.

An effective strategy for this level is to deliberately cause the other monsters present on the level to attack the Spider Mastermind. The Spider Mastermind will then become preoccupied battling with the other monsters and will ignore the player's fire until the attacking monsters are killed. For example, you can move behind a Cacodemon, and the spiderboss will try to fire at you, but will fight the Cacodemon instead. Fire at the spiderboss from behind the cacodemon, but don't fire at the Cacodemon! Eventually, the spiderboss will kill the Cacodemon, but the combined forces against the boss will cause it to die faster. See the demo below.
