The Haunted: Hells Reach / TYA Windows game

The Haunted is a fast paced thirdperson action horror game that focuses on delivering an intense multiplayer experience. Your goal is to liberate cursed places and survive the assault from the minions of hell. The game features several multiplayer modes such as coop-survival, demons vs. humans and demonizer. The Unreal Engine 3 powered graphics lay a perfect tone for the gameplay.

• Playing as human is action focused survival gameplay with a huge
  arsenal of weapons and melee attacks, total freedom in movement and
  brutal, intense combat.
• The minions of hell come in many variations and approach from
  everywhere to give you the feeling of a real fight for your life. There
  is no place to hide, together or alone. In addition to that, watch out
  for dangerous traps and environmental hazards.
• Some multiplayer modes can have players taking control of vicious
  demon masters. Here you can spawn monsters and play them by yourself,
  or place traps and trigger the environmental hazards to create a
  unpredictable threat for the humans.
• The monsters are harrowing and locations feature a classic horror atmosphere with a remarkable western-gothic style.
• Solo Mode: The singleplayer mode pits one human against the forces of evil.
• Coop Mode: Up to 4 human players have to make a stand against the
  undead. Send as much as possible back to hell and redeem the souls of
  fallen comrades.
• Battle Mode: 4 Human players against 4 demons.
• Demonizer: Similar to coop, but each dead human will turn into a demon until no one is left.
