Resident Evil 5/Chapter 3-1

Marshlands

Section 1: form the broken slate
At the start of this section, Chris and Sheva are standing on a dock next to an airboat.

Run up the small dock and pick up the first piece of the slate. On the left is a skull with a gem on it. Slice at it with the knife and then pick it up. To the right is a Jeweled Beetle hanging on a pillar (you can grab it without hitting it).

Go back to the dock and get on the airboat.

From the initial island, drive north and follow the yellow objective (the same location as the locked door symbol). Get off at the island there and insert the first piece of the slate into the door. To the right is a small fenced area with a scroll on the ground. Pick it up and three locations will be marked on the minimap. These are the locations of the remaining slate sections.
