Fratricide
Common44.0%Objective
Do whatever it takes to survive.
Euthanise the Weighted Companion Cube. In Test Chamber 17 the game hands you the Companion Cube to weigh down a button, then - to open the exit - insists you drop it into the Emergency Intelligence Incinerator. You have to do it to finish the chamber, so despite the grim name (and GLaDOS's guilt-tripping) its completely unmissable. Pour one out for the cube. :(
