We posted what we considered a cracking deal for this one last week, but we’re here now and Play has dropped the price even further for the PC version of Valve’s First Person Puzzler. This deal isn’t quite the jump that we saw last time as it will ensure you save £2 over Gameplay’s next best price, but when you consider that this delightful game has now fallen below the magical £15 mark it definitely makes it worth bringing to your attention. What else can be said? It’s worth every penny (and probably more) as it builds on the original’s premise by expanding the story, and gives you more puzzles to get your brain working over. It also gives us more GlaDOS, which is always nice.
