A Force Field is a projected energy barrier present in the Dead Space universe. Although this technology is rarely seen used, it is present in at least two Dead Space games. The primary function of this technology appears to be the containment of atmosphere aboard a spaceship or space station after conventional systems, such as emergency bulkhead doors, have failed.
They appear to be translucent with a blue glow and visible particles towards the edges.

Chapter 11: After Isaac crashes an escape pod back onto the sprawl, an area of force field is seen, presumably it became active after the escape pod damaged a section of wall.
