Obviously, that Samus won't be able to Screw Attack, fire missiles, or turn into a morph ball. It is based off the part of Zero Mission after you slay the Mother Brain but lose your suit when your ship is shot down. This Samus has different abilities. She's probably more melee oriented, seing as she has an energy sword.
In Zero Mission, she also had a stun pistol that could knock out Space Pirates for a bit, but not kill them. I suspect that this will be treated something like the standard laser gun SSB item from the first two games, only maybe with some sort of paralysis effect.
And honestly, it's Samus in a skintight cyan jump suit. How can you complain about it?
