The suit has three slits in the helmet's plating covering Isaac's face, indicating it is a Level 3 Suit.

In the Dead Space: Aftermath, the engineer crew uses a RIG similar to the level 3 suit, but with a grey finish and a folding face cover.

Similar to the Advanced Suit from Dead Space 2 and the Arctic Survival Suit from Dead Space 3, the level 3 RIG suit appears to act as a symbol of the first Dead Space.

The suit appears frequently in early screenshots of the game as well as in advertisements and marketing productions of the game.

This suit became the defacto representation of RIG suits in the franchise.

On the green pouch on lower-back area of the suit, an ID-card is visible, presumably belonging to either Isaac or the suit's original owner.
