Taken on its own merits, Metroid: Samus Returns is a brilliant action game. Movement is snappy and tight; combat is exciting and demanding; and the environment swims with as much color and life as you can cram into a hostile alien cave system full of the galaxy’s most terrifying bioweapons. It’s a fun ride, but it all feels too safe. Metroid II was cold, isolating, almost hostile to the player. You could feel the depth above your head as you descended. This 3DS remake doesn’t do that, trading the atmosphere and dread of the Gameboy original for spectacle and action.
