'''''Portal 2''''' is the sequel to [[Portal]], the puzzle-platform game originally released as part of [[The Orange Box]]. It features significant upgrades across multiple aspects of the game, including its engine, graphics, physics, and gameplay systems.

It also features a larger single-player campaign, new characters, a co-op mode and an in-game level editor.

Its development cycle was particularly complex, going through multiple different storylines and design choices, especially BTS (Behind The Scenes), resulting in a substantial amount of development material and unused content.
