9. Throughout Chapters 7, 8, and 9, all feature which type of environments requiring Isaac to use RIG thrusters?
From Quiz Dead Space 2
Answer:
Zero-G
Chapter 7 of the game takes Isaac, Ellie, and Strauss through Titan Station's Solar Array and Fuel Processing Area on their way to the Government Sector and, unsurprisingly, it turns out to be one of the most dangerous sections yet. By realigning the dishes towards the center unit while floating in the Zero-G environment of space, he can power up the station once again. Unfortunately this is used against the protagonists later on in Chapter 9 when the beams of the array are realigned to destroy their tram rail. This is preceded by the customary Zero-G float through the grinding, chopping, and flame-shooting bowels of the fuel processing center. It's not a safe place.
When the tram becomes unusable, Isaac decides that the only way to reach the Government Sector after this point is by taking a detour through none other than the USG Ishimura. Of course.
