22. Portal (2007)
Portal is one of the most unique, imaginative spins on the FPS you’ll find. A shooter with no killing, the player is given a novel tool (the portal gun) and tasked with completing a series of puzzles. Though brief, it is an immensely satisfying gaming experience. Each puzzle teaches a different way to use the portal gun, all in preparation for the game’s third act where you leave the structure of the test chambers and must escape the facility using everything you’ve learned along the way.
The pitch black sense of humor elevates everything, and though some might be disappointed by the short run time. However, every minute of the game is a delight.
