Upgrading Isaac Clarke's engineering armor is one of the most critical steps to surviving the Necromorph infestation in the Dead Space Remake. Beyond increasing overall health and inventory capacity, collecting every available suit allows players to experience the full aesthetic range of armor designs. This guide outlines how to acquire each standard upgrade, locate essential suit schematics, and unlock special cosmetic options throughout your journey.

Standard RIG Progression and Store Purchases

Isaac begins his ordeal aboard the USG Ishimura equipped with the default Level 1 Standard Engineering RIG. Players can purchase the Level 2 Suit from the store near the end of Chapter 1 for 10,000 credits to immediately gain 18 inventory slots and a five percent damage reduction boost. This initial upgrade provides a solid foundation before exploring deeper into the dangerous vessel.

Finding Key Suit Schematics Across Chapters

Higher tier suits require locating specific schematics hidden within the ship's decks before they can be purchased. The Level 3 schematic is located in the EVA Prep Room during Chapter 4, while the Level 4 schematic rests in the Equipment Workshop during Chapter 7. Finally, the Level 5 Advanced Engineering RIG schematic is found on a bench inside the Crew Quarters locker room in Chapter 10.

Unlocking the Ultimate Level 6 Suit

The highest functional armor tier in the game is the Level 6 Advanced Soldier RIG, which becomes accessible only in New Game Plus. After finishing the main story, players can buy this powerful military armor at the first store in Chapter 1 for 99,000 credits. It grants an impressive thirty percent armor protection along with maximum inventory capacity.

Cosmetics and Deluxe Edition Suits

In addition to standard suit upgrades, players can customize Isaac's appearance using special cosmetic suit skins. Options like the Infested Suit, Lone Survivor Suit, and Sanctified Suit can be selected directly from the store storage if unlocked through DLC or special campaign feats. Equipping these unique skins lets you customize your look without sacrificing any of your current RIG stats or inventory capacity.
