Details released on first Batman DLC pack

Eidos has released new details today on the new DLC for Batman: Arkham Asylum.

Free to download on Sept. 17th from the PlayStation Store, Xbox LIVE Marketplace and Games for Windows LIVE Marketplace, the Insane Night Map Pack will offer two new Challenge Maps, one combat challenge and one predator challenge.

In the Totally Insane combat map, Batman will have to lay the smackdown on wave after wave of escaping inmates in the records facility.

Meanwhile, the Nocturnal Hunter Invisible Predator map will force the Caped Crusader to stick to the shadows and utilize his gadgets and Arkham's watchtowers to take out the Joker's henchmen patrolling below.

The 2nd free downloadable content, called Prey in the Darkness, is set to come out a week later on Sept. 24th.
