''Portal'' did not feature pistons until late in the game, during Chell's escape. In ''Portal'', pistons serve primarily as a hazard, as a player who is caught between a piston and a wall will be crushed and killed. That said, there are times where Pistons are instrumental to a player's success, such as providing a bridge in [[Portal Escape (Part 1)|Escape 1]] or propelling the player through a portal in [[Portal Escape (Part 2)|Escape 2]].

Two types of piston are present in ''Portal'', a cylindrical piston and a rectangular piston. The rectangular pistons are only seen once and are used to elevate Chell in order to for her to create a portal on an otherwise unreachable surface.
