How to kill the three hydra boss
You have to hit them until they fall over. You have to jump on the boxes on the left and right (depending on which side you start with), and then jump on the platform until it falls and sticks in the head of the little hydras. Then, you have to climb up the cargo net to the big hydra (be patient) and you have to get him to where you can use circle to activate the minigame to knock off the pole. Once you get him down, push [Circle] and pull him on the pole. Then you have to go inside the big hydra and find the guy and watch the cutscene and take the key. Go back to the beginning and thats how you beat the 3 hydra boss.

Move faster
Press [Right Analog-stick Forward] to roll forward, then press [R1] to execute a Hermes Rush shoulder charge before the roll ends. Repeat this to move faster.

Skip conveyer belt area
When you first walk in to the conveyer belt area right before pandoras box you barely go past the entrance as to not activate the battle with harpies and arrowers. Immediately walk as far as your can to the left or right with running into a conveyer belt. Then walk forward next to the conveyer belt until you reach the first pedestal. Jump on it and you should be home free. Now you can liesurely walk to pandoras box without a battle.

The whole idea is that there is an area near the entrance that if you walk in it you will initiate the battle. By walking as close as you can to the edge you are not "tripping the trigger" per say.
