Valve, creators of the game franchises such as Half-Life and Counter-Strike, just launched a free Portal 2 DLC titled “Perpetual Testing Initiative” for the PC and Mac.
The “Perpetual Testing Initiative” allows players to easily create, share, and play Portal 2 puzzles. The Initiative comes with a simplified puzzle maker that allows that creation of mind-bending puzzles without ever leaving the game.
