For the final part of Varuna Point, you’ll need to operate a crane to drop a bunch of concrete down.
To do so, you will have to find a crane key first but this is one of the last steps in this area.
Here’s how you can find the crane key in Raft.
Pre-requisites to finding the crane key
The crane key can only be found after you’re done with all the underwater stuff.
You have to complete the following in the respective order:
The crane key and a wind turbine blueprint are both on the table in a room. This room is directly accessible after you’ve beaten the rhino shark. You can use the link on how to defeat the rhino shark for more info.
How to climb up the tower crane
To climb up the crane, swim towards the right-side of the building where the tower crane is.
There are some elevated walkways.
Continue to climb up and you’ll face some wild animals. Some of the climbing requires jumping on pillars and so on.
Eventually, you’ll reach a bunch of ladders going directly up.
You will then see the crane operator room.
Insert the key that you found earlier and move the lever to drop the concrete
Drop the concrete
The big net of concrete will drop onto the opposite building and create a big hole.
Use the zipline beside the crane operator room and you’ll zipline all the way to the other building.
New location: Temperance
Jump down the newly formed hole on the building and you’ll eventually reach a room.
In the room, you’ll find a blueprint for advanced battery and some notes.
You will now have unlocked the new location called Temperance. The coordinates are #1101.
This should be the end of Varuna Point’s exploration.
