Alternate title: They Played I and II, Now Ponies Play Doom III

It wasn't long ago that Equestria squared off against the denizens of Hell. Now, Hell is back for revenge, this time with someone new in charge.

The two sides are ready for battle. The question is, will the victors be standing on four hooves, or two?

What happens when Rarity becomes obsessed with the game Doom II? A lot, actually. Not only is she seeking help from unlikely sources (like Discord) to help beat the game, but she's in terrible trouble. It turns out the Icon of Sin is not happy that a pony is defeating his army. What distance will he go to put a stop to Rarity's success?
