How about a new Batman: Arkham City trailer to make sure this Monday is one of your best days this week? This time around, Rocksteady has decided to feature The Riddler and his quest to mentally dominate Batman.

Riddler, of course, was an exceptional addition to the world of Batman: Arkham Asylum. While he never made an explicit appearance, Nigma made his presence known through voiceovers and fantistically unique riddles scattered across the island. Now it seems that Rocksteady has taken the fan favorite character and made him a real threat for Batman.

Edward Nigma, much like the rest of Wayne's rogue's gallery, wouldn't pose much of a phyiscal challenge for Batman. However, the mental challenge that might away players in every nook and cranny of the playable space of Gotham City might be enough to undo the hero's intended justice.

Or it might be enough to push Arkham City from a simple sequel to an outright glorious follow-up to what was a surprise hit from a few years back. Batman: Arkham City is set to release for the Xbox 360, PlayStation 3 and PC on October 18th of this year. The game was also announced for the Nintendo Wii U at E3.

As more news comes for the title, we'll have it.
