While playing Dead Space (2023) Remake you may stumble across Schematics. These unlock various items for you to purchase in all the shops scattered across the Ishimura. There are 13 Schematics in total to find, but only 12 are needed for the Merchant. This guide will list all Schematics you can find in Chapter 4.
Collect all Schematics.
Schematic 1 – Intermediate Engineer Rig
There’s only one schematic in Chapter 4, but it’s a pretty significant one. This can be found inside the EVA Prep Room which will be on your right as you go through the Exterior Access corridor. When you enter the room, the schematics will be on the bench at the back. If you follow the story until you have the “Calibrate Three ADS Cannons” objective you should be in or near the Exterior Access corridor where the EVA Prep Room is.
The schematic allows you to purchase the Intermediate Engineer Rig for 22,000 Credits at any Store. This suit will offer you a 10% Armor rating and 22 inventory slots.
