			* {{Spoiler\|In both games (reduced in ''Portal'') are some "timeline" levels that tell the player about history of [[Aperture Science]].

			* Both games feature the same protagonist.
			* {{Spoiler\|Both games feature the same antagonist (in ''Portal 2'', only until the end of chapter 5, ''The Escape'', when [[GLaDOS]] was replaced with [[Wheatley]]. However, it doesn't change anything about the fact that the antagonist is the [[Cores#Central Core\|Central Core]].)}}
			* Most testing elements (such as the Weighted [[Weighted Storage Cube\|Storage]] and [[Weighted Companion Cube\|Companion]] Cubes, [[Sentry Turret\|Sentry Turrets]] or [[Super Button\|Super Buttons]]) are the same in both games.
			* {{Spoiler\|Both games feature backstage areas known as [[Doug Ratmann\|Rat Man]] Dens.}}

			===Differences===
			* {{Spoiler\|In ''Portal'', [[Portals\|portalable]] walls are made of concrete blocks and non-portalable walls are composed of small brown metal cubes. In ''Portal 2'', both types of walls are made of an unidentifiable material resembling plastic, although probably also composed of metal, as seen in broken [[Panel\|panels]] of chapters 1-4 (''The Courtesy Call'', ''The Cold Boot'', ''The Return'' and ''The Surprise'') and while walking through the maintenance areas of chapter 5.}}
			* The maintenance areas were significantly revamped.
			:* {{Spoiler\|In ''Portal'', all maintenance areas are claustrophobic and creepy crawlspaces in a state of serious disrepair.
