In which video game does an evil AI character named GLaDOS appear?

• A. Doom
• B. Halo
• C. Minecraft
• D. Portal

Answer: (D)

GLaDOS is a sentient artificial intelligence that runs a testing facility in Portal. The game centers on solving portal-based puzzles while GLaDOS toys with and tests you through witty, sometimes menacing dialogue, making her the defining antagonist and voice of the experience. This character and setup aren’t part of the other games listed—Doom is about fighting demons, Halo focuses on a space opera with AI companions like Cortana, and Minecraft is a sandbox about building and exploration without GLaDOS. So the game that features GLaDOS is Portal.
