You have no idea how difficult it is to make Naruto Shippuden: Ultimate Ninja Storm 3 Full Burst fit into a headline. But yes, it’s currently on sale on Steam.
The first Naruto game to hit PC is on sale on Steam until Monday 13 October, for the grand price of £6.79. If you have any familiarity with Naruto at all (and don’t hate it) then this particular light fighting game is easily worth that price. Be warned that you will almost certainly need a gamepad, though.
Honestly, I enjoyed it a lot more than I did its sequel, Naruto Shippuden: Ultimate Ninja Storm Revolution. The latter has more characters and a few improvements to the fighting engine, but a far, far weaker single-player mode and a much heftier price tag. At this sort of price, though, Ultimate Ninja Storm 3 is likely worth a punt.
