Chapter 2: The Lost Vault, featured in Transformers: Rise of the Dark Spark, includes 3 audio logs collectibles that must be located and retrieved. The video guide shows where to find them.
Audio Log 1 – In the starting area, after you cross the pool, but before reaching the entrance, turn left, and go around the large lava waterfall on the wall. Eventually, you will find an upper platform, and on it the first Stalker’s Audio Log.
Audio Log 2 – The second Audio Log can be found after you defeat the three insectoids, and after you reunite with Starscream.
Immediately after the cutscene you will be on a bridge above lava, and the Audio Log will be right below the said bridge. Look for a large pipe on the left side of the same bridge, and jump on it to reach the collectible. Use the smaller pipes on the other side of the area to get back to Starscream.
Audio Log 3 – When you reach the entrance to the vault, clear the area, and approach the large door. Eventually, you will trigger a cutscene, and gain control over Starscream.
Switch to the plane, and fly up looking for a hidden area, behind a wall, and above the vault’s door.
