From Metacritic:
In a post-apocalyptic world populated by sentient robots, its inhabitants are once more threatened by an old foe. Virus Army, after having been defeated decades ago in the past, has re-emerged from the shadows. Their goal? Complete world domination. Severely weakened Guardian Corps are left with no other choice but to call upon a hero of the previous war: the lone operative, Kai, who harnesses the powers of the elusive Gravity Circuit. As the world's last line of defense, journey through futuristic enemy controlled locales, and take down the evil mastermind behind the chaos. Reminiscent of classic platformers from the 80s and 90s, with action dialed to maximum, channel your power into your fists and send foes flying, or grapple them to get up close and personal. In your quest you will acquire many new powers, which will allow you to go even further beyond!
