Defeat Thanatos on Hard in 1 minute 30 seconds or less.
Right at the beginning of scene 10 you will fight Thanatos.
In that room where you fight him are red exposive spots on the ground.
Just shoot these spots when he is near to them. Do this 4-5 times and then shoot him directly, cause he is not always near to the spots and it will then take more than 1:30 minutes to beat him.
