Unlocking fatalities
In Death By Elimination, there will be a series of characters. Defeat all of them and you will get your character's fatality. Complete it twice and you will get his or her second fatality.

Alternate fatalities
When certain conditions are met, each fighter can perform an alternate fatality.

Head Rip: Kill your opponent when they have lost both their legs.

Anvil Drop: Kill your opponent when your fighter has lost both their legs.

Matrix Decapitation Kick: Kill your opponent when your fighter has lost both their arms.

Cut off the celebrity's arms or legs to do an alternate death kill. For example, Carmen Electria has saws. Keep hitting the other celebrity with the saws and either the arms or legs will fall off. Note: Once you take off a celebrity's arms or legs, they use an attack that throws them at you. Although it does not take off too much damage, you will not be able to block the attack.

Marilyn Manson: Fatality
When the game says finish him or her, press [Circle] + [X], then [Left]x3. You will twist their neck for a fatality.

Easy wins
Play as Dennis Rodman. When the fight starts, get close to the opponent and keep pressing [Triangle]. The basketball should keep on hitting the opponent on the head for an easy win.
