Battle
Medusa has snake hair that you need to fight so you kill them by tying there necks around and throwing them at her she starts pulling them and they blow up and she starts falling, repeat this over and oer until the last head which is like the others but has heaps of spikes coming out of its back and breathes fire. After she is still hanging with her other bits of hair and you fight her then Beowulf jumps up and slices her hair of then she is being fought until his dead.
