Entropy Zero series is a Masterpiece!

This is probably the best HL2 mod I've ever played. Instead of the good guy you play as the bad guy and kill the good people.

This kind of reminded me Half Life Opposing Force where you play as a HECU Soldier: Adrian Shephard, but integrated graphics from first HL to the second. Aiden Walker (3650) and Adrian Shephard would work together to destroy the humanity and make them slaves for Breen.

And also a good detail I like about the Rebels is that they are very accurate. More accurate than Combine soldiers and Metro Cops. The Combine's humanity got sweeped; got brainwashed before being a Combine soldier, which makes their aim bad. Which means a single Rebel can shred you in 2-3 seconds (Probably more if you're playing on Easy difficulty)

The playthrough is somewhere in 2-3 hours. If you want 100% completion; probably somewhere 5-8 hours to get all achievements.

I HIGHLY RECOMMEND PLAYING THIS MASTERPIECE GAME! IT'S FREE AND HAS A SEQUEL!
