in addition to the melee counter, there are four aeon abilities: detect breakable blocks, armor, rapid fire and slow-down time

you get new cool powers, though instead of new armor, all you get is a lazy glowing green glow, instead of a speed ability, you slow everything else down, rapid fire and a pulse scanner that helps you find hidden blocks, comes in handy when looking for items and tracking metroids and power ups, something neat of the portable

Other Aeion abilities allow Samus to do such things as slow down time, utilize a rapid fire effect or put up an additional shield to soak up some damage

enemies that eat away your precious aeon energy, which you may need for later have to kill them with rapid fire and they get annoying the more you see

A straight-forward Metroid experience, "Samus Returns" is easy enough for newcomers to the series, and has a few new features to keep veterans stimulated, such as parrying attacks, and a panoply of amusing armor abilities which range from shielding and rapid fire to sonar pulses for mapping out the immediate vicinity

You can also rapid fire your beam, slow time, and gain a shield which blocks damage at the cost of energy.

If you want an example, I spent about an hour in the first area dying repeatedly before I even faced the first Metroid because I really didn't want to use the move, so I watched a video about the game to find out what I why I sucked at
