Entropy: Zero is a free-to-play fanmade Half-Life mod (dependency on Half-Life 2: Episode Two to launch) game developed and created by Breadman. The game was released on Steam on October 10, 2017. As of April 12, 2020, Entropy: Zero has received more than 2,600 reviews, with a rating of Very Positive (between 80% to 94% positive reviews).

A sequel to the game has been officially announced, named Entropy: Zero 2 where you take the role as an Overwatch Elite unit, making it one of the few games where the player takes the role as a Combine unit, and not the opposition.


You play as a stranded Metrocop, left for dead in the abandoned City 10. You fight Rebels and Zombies along the way.


Bad Cop

The protagonist villain of the game.

Barney Calhoun

A resistance member working undercover for Civil Protection.
