Portal Stories: Mel - Trailer

Portal Stories: Mel is a substantial, free modification built upon the Portal 2 engine, offering players an expansion of the puzzle-adventure experience in the Aperture facility. Released in 2015, this mod introduces a new protagonist, Mel, and a fresh narrative involving an unknown threat and a new personality core. Gameplay centers on mastering the core portal gun mechanics—spatial reasoning, momentum, and physics manipulation—to solve increasingly complex environmental puzzles across new test chambers. As a community-made project, its value lies in delivering a complete, new campaign leveraging the established mechanics.
