This week has been a good one for Portal lovers. First Valve released some new Portal 2 Gamescom screenshots. Then that new Wheatley trailer came out. This was followed up yesterday with the release of a pair of new gameplay trailers. And today, it pleases me to bring you a new teaser trailer for Portal 2’s intriguing co-op mode. We don’t know too many specifics about what the mode will entail, but I was on board as soon I found out that you play as a pair of robots trying to make their way through Aperture Science. It’s just so damn quirky and adorable; I can’t stand it. Check out the trailer to see what I mean.
