Portal – Hall of Science is an extremely well-designed map which has been inspired from the Portals games, developed by Valve, and the Portalgun mod, created by iChun.
Indeed, the map follows exactly the same sequences as in Portal. You will begin your adventure in some additional rooms that are very faithfully reproduced. There are also some new test chambers to give players the impression when playing the game. Don’t hesitate to install the map to play a fully playable and functional map!
18 Tests chambers from the game. 13 additional rooms. The “Second part” of the game. “Her”. All.
