Cloned Cube is a Portal mod. It takes place after GLaDOS' fall in Portal. You assume the role of Chell's secret clone. You have to escape or else you may just be tested to death. There is one obstacle. CUBiS is trying to kill you.
Hey, Cloned Cube turned ONE year on August 2nd, AKA yesterday! Man I've been developing this mod for a full year now.
Please remember that you won't receive cake at the party.
