The best Dead Space suit upgrades appear as elusive schematics scattered across the Ishimura, and taking the time to track them down can be the difference between life and death - or worse, a full inventory. Resource Integration Gear, otherwise known as RIGs, are specialised suits designed to assist the wearer in a number of ways. RIGs come with built-in health management and navigational systems as standard, but that's only scratching the surface of what benefits they provide.
Isaac begins his ill-fated tour of the Ishimura while wearing his default suit, the appropriately named Standard Engineer RIG, but it doesn't offer much in the way of protection against necromorphs. In order to survive, you must keep an eye out for Dead Space suit upgrades. Each one grants additional armour and inventory space, both of which will serve you well in what's shaping up to be one of the best PC games of 2023.
