There’s no such thing as a free Borderlands 2 weekend on Steam, my grandmother used to say. Well, granny, look who’s the “stupid-faced, manchild, crushing disappointment to the Walker family” NOW. Gearbox’s cel-shaded gabbling co-op ARPGFPSOMGWTF is currently experiencing rather big discounts, and is available to fart around in (after a fashion) from now and all weekend without your wallet shedding a single tear. And indeed save a bunch on all manner of 2K games from now until Monday, including XCOM Enemy Unknown for £3.75 and Enemy Within for £6.60. Or all three BioShocks for £6.80.
