Rumour - First Batman: Arkham City details emerge from GI

That didn't last too long, did it?

The quickly and aptly-named ArkhamCity.co.uk has gained the first details on its namesake from the latest issue of Game Informer.

The story sees Two-Face trying to assassinate Catwoman to get respect in the criminal underworld while inside Arkham.

As for the whole Arkham Asylum-Arkham City thing itself, Black Rock prison and Arkham itself is "unfit" to hold inmates, so Quincy Sharp, who was running for mayor in the original but isn't anymore, has bought off a part of the slums and walls it off to create Arkham City.

Hugo Strange will be in charge of Arkham City, according to the mag.

As for gameplay changes, all the gadgets you collected during Arkham Asylum will be available to you at the start of the sequel.

You'll also have more puzzles, more Riddler challenges, both of which come back from the original, and side missions which are new to the series.

This time around, Batman can counter two attacks instead of just one, and he also has a smoke bomb.

Gangs will also roam about the city, with info collected onto Batman's criminal database.

The Rocksteady sequel was announced last week for a fall 2011 release on PS3, 360 and PC.
