Fight off your attackers in Mighty Viking. Wait until the Viking’s foes come within range of his battleaxe and smite them. Make sure you land your hits, because if you miss your axe will get stuck in the ground and it’ll take your Viking some effort to recover. After every wave of enemies, the dragon will appear for a tough boss fight. Watch the dragon’s shadow as it flies over and figure out one which side it’ll land. When the dragon breathes a ball of fire at you, you can try to whack the fiery projectile with your axe to shoot it back at the dragon’s face.
