You firstly need to power-up all 6 generators scattered around the map.

Once powered there will be staff items scattered around the map in no mans land aswell at the trenches in the soawn area (so use a spade to uncover them.

Once found, you need the microphone and the music record to be able to teleport to an ancient place where you will retrieve one stone that corresponds to the staff you have teleported there to complete (so fire is red and so on...).

Once all staff have been built and you have found all correct parts (some will be in the giants that walk across the land, to get in them shoot the left foot and jump inside of the robot's underside foot where the light should appear).

You will then teleport back and head over to the pack a punch machine (underneath right to the bottom) where you will build the staff and complete the others in that same way.

You can use the staffs but cannot upgrade them.

Boxes around the map that require souls are also things you will need to fill up. I am not fully aware of what that do but i think they give you certain pwers when pressing b/RS instead of your knife.

Once passed the staffs i think you have to use the levers to find the right combination of colours where the pack a punch is. This is where i initially got stuck and was unable to carry on.

If you need questions answered please ask, ill try and help you as best i can.
