[...A new trailer for zombie shooter Left 4 Dead has emerged from the Leipzig Games Convention, and unsurprisingly it's full of zombies being shot.Highlighted in the clip is a gorilla-like oversized zombie that apparently combines superior stamina and strength to become something of a typical second-tier first-person shooter enemy.I'll never get used to zombies that are anything but George Romero's shambling hordes, but after Portal I'm almost honor-bound to buy everything Valve puts out.See Also:Le]
