About Portal
Portal was developed by Valve. The release date was October 9, 2007. The genre is characterised as Action.
Portal™ is a new single player game from Valve. Set in the mysterious Aperture Science Laboratories, Portal has been called one of the most innovative new games on the horizon and will offer gamers hours of unique gameplay. The game is designed to change the way players approach, manipulate, and surmise the possibilities in a given environment; similar to how Half-Life® 2's Gravity Gun innovated new ways to leverage an object in any given situation. Players must solve physical puzzles and challenges by opening portals to maneuvering objects, and themselves, through space.

Where to buy Portal cheap
Portal launched at $9.99 in 2007. The cheapest currently listed total is $7.59 at Kinguin, which is -24% off the recommended price.
Official stores start at $9.99, so the keyshop route saves $2.40 on this title. That saving comes with a trade-off: keyshop listings are resold keys, and a listing marked as a gift is not a standard key. The key type column above tells you which is which.
Feed update times differ by store. Confirm the current price, product type and activation region on the store page before completing the purchase. Our comparison methodology explains matching, ranking and checkout-fee limitations.
