BigHero.Io is a challenging multiplayer game with a premise that's very similar to 'Agar.io' or 'Slither.io'. Sharing not only its simple yet fun mechanics, it also comes with sleek minimalist graphics.
BigHero.Io's premise is very straightforward: kill as many enemies as you can before they kill you. Using the joystick located on the left side of your screen you control how your protagonist moves, and using the button located to the right of your interface you carry out attacks. Each enemy you beat rewards you with more experience points, in turn increasing your weapon range.
Despite its simple appearance, BigHero.Io comes with heavy doses of strategy because, among other things, you have to carefully measure when to perform each of your attacks. Though, the amount of time it takes to do so will leave you vulnerable for a few moments to any opponent who is close enough to take advantage of the opportunity.
One of the most interesting features that BigHero.Io comes with is its complete system of achievements and rewards, along with small challenges that will allow you to unlock new skins for your character before performing more or less demanding feats during your games.
