Blood II: The Chosen -- The Nightmare Levels is the official add-on pack for the original game that revolves around the return of Caleb and The Chosen to Otherworld where they meet the Nightmare, a psychic terror threatening the Wasteland. Included are six new multiplayer levels and one new mode -- playing soccer with the heads of your enemies in Zombie Head Soccer!
Choose to play as any of several new multiplayer creatures such as the Soul Drudge, Prophet, Cultist, and others. Employ new weapons that include a combat shotgun, a single barrel semi-auto fire, and a heavy-duty military purveyor of death that shoots shells as well as smoke clouds. Or, try your hand with the Flayer, a grappling hook on a bungee cord that can be used to flay an unsuspecting enemy alive.
Enemies include Tchernobog's Cultists, the human soldiers from the original Blood, the Nightmare, an overgrown Hell Hound, and the cute and annoying (and sometimes deadly) Gremlins, who attack in packs but love to simply taunt and harass you. The game supports gamepad, joystick, mouse, and keyboard interfaces.
