Though we've only had Steam for a few weeks, by now the lot of. us have undoubtedly played through Portal's incredibly addicting storyline and figured out that the cake really isn't a lie. Unfortunately, computer gamers everywhere will have to wait even longer to get another slice of cake, as Valve doesn't plan on releasing the sequel until 2011.
Unlike anything we’ve ever played, Portal’s brilliant, mind-bending platforming is the pinnacle of puzzle games. Some may scoff at its brevity (it’s only three or four hours long) but it’s so clever and cool that you’ll want to experience it again, if only to see what layers of depth you missed. There are enough spoilery distractions along the way that you probably won’t catch ‘em all. Keep these tips in mind while, ahem, doing what you do in Portal.
