>Samus Returns
What did Nintendo mean by that?
It's just a change up of the name "Return of Samus" since it's not a 1:1 remake of Metroid 2.
It's stated to have extra portions similar to Zero Mission and we already have seen changes to the combat and level design (ledges you can grab on to, a melee counter / parry, aeon abilities, etc.).
Samus has returned and only our guy Metroid can defeat her.
