The cynical, sharp-tongued, door-smashing zealot dubbed 'Bad Cop' is back in action. Lead a squad of Combine synths and soldiers on a northern mission to seize Dr. Judith Mossman. Follow in Gordon Freeman’s footsteps at Nova Prospekt. Venture into the enigmatic 'Arbeit Communications' base. Uncover hidden truths beneath the surface. Pilot an APC across the frozen tundra. Challenge the rebels at their front lines and reveal a secret buried in time.
Civil Protection Unit 3650, also known as Aiden Walker, was reassigned to an offsite team after a conflict involving several other CP units. It is from this point that the events of the original *Entropy: Zero* begin. Following the conclusion of *Entropy: Zero*, Aiden Walker is revived as an Overwatch Elite. His mind and consciousness were restored, as he was believed to be the final remaining copy. His mission is to track down Judith Mossman and uncover the true nature of her objectives. While *Half-Life 2* is set in the urban environment of City 17 and its coastal surroundings, *Entropy: Zero 2* is primarily set across the expansive frozen tundras and mountainous regions where the Borealis was hinted to be hidden. In fact, the video for *Episode 5* briefly displays the letter “B,” which aligns with the name “BOREALIS” seen on the hull of a cargo ship believed to be transporting it. The mod includes three possible endings and one hidden ending, each determined by the player's choices during the game's final chapter.
