Ninja Gaiden Sigma is to get a new lease of life in September with the release of some DLC. Scheduled for the 6th of September is the first part of the DLC, a new Survial mode. Expect to be pitted against scads of evil-doers to do away with and survive against. Awesome.
Two more bits of DLC are expected in this batch, to be released after the Survival mode.
Happy Ninjaing, folks.
