"Yell "Dead Cell"" is a theme that plays in Metal Gear Solid 2: Sons of Liberty. As the title would suggest, it serves as the theme music for various boss fights during the Plant Chapter of the game, primarily against characters affiliated with the group Dead Cell.

It features a techno-beat as well as occasional screeching throughout.

Portions of the theme appear in DreamMix TV World Fighters on the Big Shell stage whenever the Harrier appears.

It is also a selectable track in Super Smash Bros. Brawl, with the theme being slightly extended.

Finally, the theme appears in the BGM for the version 1.02 update for Metal Gear Online 3, titled "MGS2 DEAD CELL."
