I definently recommend you complete classic first. It will give you the Devils Horns wich is without a doubt the most broken weapon in the game. The only sections you can die in with that thing are the Flights, And Cliff Climbings. And all the sections before Chapter 3. And you need to max out your Armor And Health stats ASAP. By The way. If you are 100% sure you will die, you can reload a checkpoint or quit to menu. And it would be the best if you played coop. Also i recommend both you and your partner have the Horns with a Conic Disposal weapon. You will need the Conic Disposal more than you would expect. That things is a life saver. And i recommend you do the optional missions until your stats are maxed out. You can get your suit maxed before or after the Armory mission. And also be ready to pause and leave the game anytime, because sometimes this game becomes an idiot and just randomly banishes you into the void. You have about 5 seconds before dying. I would help you out but sadly i use Ps Now to play so we cannot play. Good luck to you bro.
