Once you step off the boat, there will be a set of stairs that you can make your way up, which will lead you to the Pump Room area.

When you’re inside the pump room, you’ll want to look for a big crack in the wall through it. There will be a set of steel beams, which will be visible, and resting on them is the Rome Exploration Guide. It might seem hidden at first glance, as it’s hard to spot.

After collecting them all, the collectible items within the DLC will automatically be marked on the map, making it so much easier for you to explore, allowing you to collect every hidden artefact, relic, or secret without missing any.
