Rachel Foley/gameplay

Ooze Rachael
Rachael's infected form shares the same moves set with the Standard Ooze. Rachael, however, has a unique move that sets her apart from the Standard Ooze asides from her appearance. Her attacks include:

Strategy (Campaign)
Unlike the other Oozes, Ooze Rachael has a large amount of health and does not get stunned easily. She is also quick in movement. Defeating her will usually burn through ammo quickly due to her agility and her considerable amount of health. It is recommended that the player faces her from a distance using a Machine Gun. If you would like to take a risk at close range then it is recommended to equip the Shotgun Windham.

After delivering enough damage to her, she will attempt to flee. If this happens you can deal additional damage by chasing her and quickly shoot her legs, leaving her crawling.

On occasion, usually after attempting and failing a multiple-hit combo against the player, Ooze Rachael may stop moving for several moments, standing in place and slumping over whilst her tongue hangs out. Whilst this may look like she is stunned, she is not and will in fact recover quickly; closing to melee range will not trigger a melee attack option and is instead more likely to result in her grabbing or backhanding the player.

If caught in the explosion radius of a grenade, Ooze Rachael will be sent flying and land on the floor, as well as taking damage. This is a good chance for a player to get some distance, shoot her further, or set up another grenade to blow her up again when she stands up.

With sufficient accuracy, a powerful weapon and a plentiful supply of grenades, it is possible to kill Rachael outside of the medical lab, where she first attacks the player, or at least weaken her so that she can be killed before the showdown in the cafeteria. In the HD remake of Resident Evil: Revelations, the achievement "By The Crosshairs" is won by killing Rachael before she attacks the player in the cafeteria.

When she dies during the first encounter, she holds the key to the bilge and drops Illegal Custom Parts in subsequent encounters.

Strategy (Raid Mode)
She is a boss at certain stages and also appears in the Ghost Ship stage with variable attributes. The strategy to defeat her is relatively the same as in Campaign Mode. The player can buy Pulse Grenades to stun her, prompting a melee attack to heavily damage her. Overall, she behaves exactly like her Campaign counterpart, fleeing when enough damage is taken.

Raid Mode
Rachael is a playable character in the HD version of Resident Evil: Revelations in Raid Mode.

With a pre-order bonus of the Unveiled Edition from certain stores, Rachael's Ooze form is a playable character for Raid Mode with her own exclusive melee attack.

Rachael reuses Excella Gionne's disco spin melee attack from Resident Evil 5. Ooze Rachael's melee attack involves her using her mutated mouth appendage to attack.
