Valve is pulling out the big
portal guns to tease the sequel to its infectiously fun puzzle-action game. An "upcoming TV spot trailer" for Portal 2 has made its way onto YouTube, giving viewers a glimpse of the gameplay and the two characters that will be featured in the game’s co-operative multiplayer component.
Portal 2 is still on track to arrive in just over a month, on April 19. Valve is offering a 10% discount on Steam if you pre-order the game now. Out of all the big PC blockbusters heading our way this year, Portal 2 might be the one I’m most looking forward to. (Thanks to CrunchGear for the tip.)
