The Plasma Cutter is the weapon you will start with and you will need to level it up before you find any others to make your playthrough easier.

This will limit you to levelling up your Suit, a primary weapon and maybe a second weapon. You can buy Power Nodes in the store for 10K credits a time, but credits will be needed for ammo and health packs, new suits, and you are not likely to be able to afford extras. There are only 67 Power Nodes to find in a playthrough of the game and that is assuming you find them all. The guide is designed to cater for everyone, not just those who may find this easier than others. For those of you who are familiar with Dead Space, this is not a Hardcore playthough of DS2 or DS3 it is significantly easier, but not to be underestimated. Doing so will take anywhere between 2-3 playthoughs and give you a good understanding of the game. I would highly recommend NOT doing this, even if you are experienced with Dead Space instead go through the game on a lower difficulty, familiarise yourself with the alterations the remake has to offer and collect all the other achievements first. Unlike the original 2008 game, you can start with Impossible difficulty straight away.

Needless to say, some may struggle with it. You only have one save file to use (save whenever you like but no multiple saves) and if you die, you have to start from the very beginning (or continue on hard mode but this voids your achievement run). Impossible has the same difficulty as hard mode, where you take more damage and the enemies take less, but with a twist.
