Dead Space 3 Chapter 11 begins when Isaac reaches the hangar where his team is waiting for him (following the events of Chapter 10), and it includes a large amount of collectables hidden in all sorts of places.
In Chapter 11, Isaac must recreate a S.C.A.F. experiment in order to be able to locate the Machine that controls the creatures, and for that to happen he needs to collect some parts to create a Probe.
Due to the higher number of Dead Space 3 collectibles that can be found in Chapter 11, players must use the hints and tips in the collectables guide below, because they reveal their exact locations.
NOTE: The guide doesn’t include the Dead Space 3 Chapter 11 Collectibles featured in co-op missions.
