LEFT THE AEION ON

Samus acquires four new special abilities which run off a gauge that’s replenished quickest via the melee counter. Aeion energy powers a shield, a scanner that highlights breakable scenery and fills in local areas on the map screen, a rapid-fire ability that makes combat less attritional, and there’s a fourth we shan’t spoil. It’s rather too easy to forget you’ve not toggled it off, however, leading to moments where you waste it all before you need it most.
