Ninja Gaiden Sigma: Survival Mode content has just hit the Japanese and Hong Kong PlayStation Network. What's interesting to note, however, is the content is not entirely free.
As a part of a series of multiple missions, the Survival Mode DLC costs 315 yen per mission (approximately USD 3). Currently, there is no official word on the price for the content in North America, or when it will be made available.
Survival Mode features themed missions, which primarily focus on Ryu's survival against a flood of enemies trying to bash him in the ground.
A total of three missions will be released for consumers to download separately. The first includes a limit of five weapons; the second is a speed mission (which requires incredible speed and skills with NGS), and finally, the third allows gamers to assume control of Rachel in the 'Rachel Master' quest.
