Metal Arena 3 provides us with amazing graphics and several upgrades for our tank. Step into the battle arena with several metal machines and crafts battling you. If you get damage, you can use the h key to buy repair packs present on the top left of your screen. Use the mouse to aim and left click towards the enemy to fire. Kill the enemy in combos so that your money gets multiplied. Your combo meter keeps reducing if you donít kill constantly.
