Resident Evil/Shout Out


 * The Chest Burster in RE 2, which evolves into something resembling a Xenomorph.
 * Wesker's Matrix style moves, and Terminator sunglasses with flashing red eyes.
 * With his glasses off, his orange cat eyes, a reference to Michael Jackson's Thriller.
 * Alexia's flammable blood attacks, an ode to Carrie.
 * Alexia's second mutation is reminiscent of the breeding form of the Queen from Aliens.
 * The cargo elevator escape in Resident Evil Zero is a shout out to the escape sequence at the end of Aliens.
 * Osmund Saddler looks and talks like Emperor Palpatine.
 * Dr. Salvador resembles both Leatherface, and Jason when he wore a burlap sack mask.
 * Resident Evil 4: The Broken Butterfly is a gun that "will make anyone's day".
 * It shares ammo with a scoped semi-auto pistol called the Killer7, which is the exact same pistol KAEDE uses in that game.
 * Another gun is named Matilda. Furthering that, the hardest difficulty in the game is "Professional".
