According to Advanced MN (AMN), unnamed sources within Nintendo Europe have revealed to it that there would be an exclusive first-person game that will feature violent swordplay and more.
AMN says that the sourced confirmed it that an un-named company will reveal an exclusive action game involving violent swordplay in the coming weeks for Revolution.
More details couldn't be revealed though from 'various sources'.
However, the other scoop AMN got was that Ubisoft is currently developing an exclusive Revolution adult-themed and incredibly violent first-person shooter codenamed 'Katana' that has some elements of swordplay combined in it.
So are the two projects related? AMN couldn't confirm it so you can see that your guesses are as good as ours!
Thanks AMN
