Another video game, “Tag: The Power of Paint,” formed the basis of surface-altering gets introduced in “Portal 2”
“Portal” and “Portal 2” have received critical praises and likewise sold millions of copies. The first game was released as part of a three-game compilation known as The Orange Box, and though intended as a short bonus feature of the compilation, was considered the highlight of the three.
The success of “Portal” led to the creation of the much longer “Portal 2,” which included both single player and cooperative player modes. Just like its predecessor, “Portal 2” also received positive critical reviews.
The story of the game revolves around a woman named Chell who is forced to undergo a series of tests within the Aperture Science Enrichment Center by a malicious artificial intelligence computer called Glados, which happens to control the facility.
Each test involves using the Aperture Science Handheld Portal Device or the portal gun that creates a human-sized wormhole-like connection between nearly any two flat surfaces.
The player-character or objects in the game world may move through portals, their momentum conserved and that allows complex flinging maneuvers to be used to cross wide gaps or perform other feats to reach the exit for each test chamber.
