Evil song: "I'm doing science and I'm still alive
I feel fantastic and I'm still alive
While you're dying I'll be still alive..."
When Chell wakes up in the mysterious Aperture Science Enrichment Center testing facility, supercomputer GLaDOS (Genetic Lifeform and Disk Operating System) becomes her friend and guide. GLaDOS promises "moist, delicious cake" as a reward for completing the various puzzles in this game set in the Half-Life universe. Unfortunately, the computer's guidance becomes more and more disturbing, with warnings of increasingly harmful side effects to the testing process.
Graffiti warnings suggest that "the cake is a lie", and when GLaDOS hints that Chell is disposable things quickly get nasty. After trying to kill Chell, GLaDOS claims it was a joke, but that doesn't stop you from destroying the computer's AI cores.
As the game's credits roll, GLaDOS sings the best end-credit song ever, the title of which, Still Alive, suggests the computer may yet have the last laugh...
Evil rating: Mwahahahahaha!
