In this section of the Guide to Rage 2, we'll show you how to unlock the charge pulse cannon. This weapon fires energy shells, which melt the enemies. To unlock the pulse cannon, you need to get to one of the Arks available in the game.
The Shrouded Vault Ark is located in the eastern part of the Sea of Dunes location. This site has the sixth level of difficulty, so you have to be careful when you go there. It is necessary to perform several story missions before you get to this location.
The Ark doors will remain locked until you complete both tasks in electro forges, located in the same area.
There, you have to destroy the reactor (example in the screenshot above). Opponents will try to stop you. Eliminate them asap in order not to get overwhelmed at the end.
After entering the Ark, go to the central post and take the charge pulse cannon.
The game will immediately show a tutorial covering the use of the charge pulse cannon. You will learn how to perform normal attacks and how the cannon works when the overdrive is active.
From now on, you can buy upgrades for these weapons.
