It was rumoured, and then it was confirmed, and then we were all like :(
For it is true: the man of bats will not strike back on PC in 10 days' time, but instead in 17 days' time. A small wait, perhaps, but we've already had to hang on for almost a month later than the console-folk. Yes, the already-delayed Batman: Arkham City PC port, mooted to be the very bestest version of Brucie-boy's semi-open-world swinging adventures thanks to various technical jiggery-pokery done with the help of NVIDIA, has been delayed anew. November 25 is the new date, which at least is safely after all Big Three of November's remaining new releases - MW3, Skyrim, Saints Row 3 - are all done and dusted and we'll have time to think about something else/sleep.
There's no word on why the PC version was delayed, and what the state of play will be for the various DLC by then. Oh well. Here's a Nightwing DLC trailer to tide you over.
He's like Batman, but not at all threatening.
