In BigHero.io you have to survive the all out battle in the arena for as long as you can. All the players are armed with a series of long melee weapons such as clubs, maces, spears, swords, and axes. Run through the arena and swing your weapon to strike your opponents, turning them into a colorful smear on the arena floor. Go on a kill streak to gain extra points and rise to the top of the leaderboard. Collect the pips and look for stray slimes to kill as well. You can collect power-ups to boost your speed, and hit the D key to make a short dash to either sprint to safety or launch a surprise attack. How long will you survive this funny multiplayer game?
