The Evolmorph (pronounced "Evil-morph") will evolve over the course of the game and features a “vanishing” mechanic where it will disappear into the ventilation shafts only to return when you least expect it or perhaps if you plan it right, into a well-laid ambush!

The USCSS PATNA spaceship introduces ‘keycards’ that can be used to access different parts of the ship. Will you kill your foe the old-fashioned way? Self-destruct the ship and escape? Or perhaps you’ll try to airlock the killer into the void!
