In answer to popular demand, Valve has teamed up with toymaker NECA to develop a life-sized Portal gun that they plan on selling in stores this summer. The Portal gun comes with LEDs that change color, making it a fine addition to any gamer's desktop arsenal of toys.
In addition to the Portal gun, NECA and Valve are also working to put out action figures based on Left 4 Dead, Team Fortress 2 and Half-Life.
