Playdek, announced today thatMartial Law, the first in-app expansion to the popular horror themed NightfalliOS game, will be available Thursday, Sept. 20, 2012. Nightfall: Martial Law will sell for $1.99 and to celebrate the launch, the original Nightfall iOS will again be offered at $.99, in a one week sale.

In Martial Law, darkness reigns and chaos threatens. Humanity looks to impose order, but can they control creatures that defy logic? New characters, new actions and new color chain combinations make Nightfall: Martial Law a brand new twist on the horror-themed, deck building game , Nightfall. A new “Feed” mechanic that allows players to get more use from their orders and a brand new “Wound” effect that lets a player increase the strength of a Minion makes the Martial Law expansion a must-have addition to the Nightfall game.

“Due to the great success we’ve had with Nightfall, we are excited to introduce an expansion pack for fans,” said Joel Goodman, CEO, Playdek. “The new additions in Nightfall: Martial Law give players the opportunity to surprise opponents as they vie to come out as victor in the end.”

Martial Law provides new Game Center Achievements (http://www.apple.com/game-center/), if users are logged into a Game Center account and new unlockable Promo cards.
