Yuletide Horror

  • Happy holidays from the Horzine team as we present our seasonal Yuletide Horrors update! Take a perilous stroll through Sanitarium and uncover its dark, ritualistic secrets while dispatching the holiday horrors skulking through its maniacal hallways. But don’t stop there! You can thwart the Patriarch’s plans to clone a legion of Zeds in the Biotics Lab Objective game mode. Seems a bit much to get done on top of decorating and gift wrapping? Don’t worry, the Horzine team developed a few new handy dandy weapons to knock the socks off those pesky, ravenous elves! As you deck the halls with guts and blood, wear some holiday cheer with our many new cosmetics that’ll put even your own grandmother’s sweater to shame! Tis the season to be slaying, and from the Horzine team, we wish you all a grand, bloody-good time!
