Characters & Builds

In Portal, you play as Chell, a silent protagonist whose 'build' is entirely defined by her ability to wield the Portal Gun. Unlike RPGs, there are no character classes, skill trees, or customizable stats. Your 'build' is your mastery of the Portal Gun and your understanding of physics. This section will focus on understanding the key characters who influence your journey and how to effectively 'build' your puzzle-solving skills. The game's narrative is driven by the interactions between Chell and the facility's AI, GLaDOS, along with the environment itself. Your progression is not about character power, but about intellectual growth and creative application of the game's core mechanics.
