Portal 2 - is a first-person perspective puzzle game. Players take
the role of Chell in the single-player campaign, as one of two
robots—Atlas and P-Body—in the cooperative campaign, or as a simplistic
humanoid icon in community-developed puzzles. These four characters can
explore and interact with the environment. Characters can withstand
limited damage but will die after sustained injury. There is no penalty
for falling onto a solid surface, but falling
into bottomless pits or toxic pools kills the player character
immediately. When Chell dies in the single-player game, the game
restarts from a recent checkpoint; in the cooperative game, the robot
respawns shortly afterwards without restarting the puzzle. The goal of
both campaigns is to maneuver through the Aperture Science facility.
While most of the game takes place in modular test chambers with clearly defined entrances and exits, other parts occur in behind-the-scenes areas where the objectives are less clear.
The initial tutorial levels guide the player through the general
movement controls and illustrate how to interact with the environment.
The player must solve puzzles using the portal gun, formally known as
the Aperture Science Handheld Portal Device, which can
create two portals connecting two distant surfaces depicted as matte
white, continuous, and flat. Characters can use these portals to move
between rooms or to "fling" objects or themselves across a distance.
Outlines of placed portals are visible through walls and other obstacles
for easy location.
