Additonal Info: Official website: Fans of the hit title Ninja Gaiden Sigma will enjoy their first content pack in less than a month. Players will soon have the opportunity to enjoy a plethora of content, starting with ‘Survival Mode.’ The first downloadable pack is tentatively set for release on September 13th.
Survival mode will prove challenging for players pitting them against an endless supply of enemies, with their sole purpose to stay alive as long as possible. This mode will feature various options within itself in the future, but the first installment, ‘Weapon Master,’ is what everyone will see in September. “Weapon Master,’ will contain five options allowing players to pick from a cache of weaponry to use while battling.
Coming in future months will be:
Speed Master – where the goal is the speed and accuracy of your attacks/kills
Rachel Master – where players can manage Rachel through five new modes
Coupled with the new content, each new packet will have its own worldwide leader board. This is great news for fans of the franchise and better news for those gamers who have already mastered their skills.
Keep tuned to PSU for future content updates and a review of the new game play.

psn id: gingo.... this is good news that they are continuing to upgrade existing games but i'm struggling to get through the normal game never mind add ons lol
@gingo...I hear you. I'm feeling stuck way too early on this game. I may just chuck it and start from the beginning. Maybe I'll be good enough by Sept for the updates.
this game is really hard, and i never get any Nimpo with Rachel lol, and i'm mad about it cause the dude with the glasses keep beating me and now they adding on more. I'm not that hardcore, i cant eve beat the special mission where you have to beat all those guys in the second part lol
thats good news.love NG
Geez I thought survival mode was already the REGULAR game itself. It's already a fight just to stay alive.
Awesome news!!!!
@wiscfan23...Thats what I did. I got so far and decided for me to progress further I would need to start over and save One Gillion times incase I made judgement error.
arf, this game is too easy. I read that xbox's version, in normal mode, was a lot harder ! I believe it's correct as I found no challenge to it !
Why do we have a lazy kid version ??!! I'm disapointed while still enjoying the game (but without challenge)
To the pals complaining it being too hard, I imagine it's because you don't read the help and apply the minimal rules. tHe most important is to block, (L1). use it quite everytime. if you don't master bloc, the game is undoable..
where da f*** is manhunt 2?
The game is really just right, Ninja Dog and Normal apply correct an adverage person can have success, Hard is hard period, regardless as how much you try to flex that it's not, Very hard, I won't even begin to speak ,but they did this to make it appeal to a bigger crowd than Hardcore gamers,
I have yet to buy a NGZ
Hay Vincent Valentine
I'm with you Blachaze. Nice to know it has new features before many people have finished the game.
