This page of the Ratchet & Clank Rift Apart game guide covers the fourth and final part of the Savali walkthrough. Among other things, you will learn how to access the huge mobile Archive and how to defeat the bosses - the Invasion Commanders.
- Find the Dimensionator blueprints
- Access the Vault of Knowledge in the Archives
- Boss Fight - Invasion Commanders
Find the Dimensionator blueprints
The final part of the mission will begin once you have freed the monks from three different temples. Gary will open a portal for Ratchet and once you go through it, you will find yourself on the new path shown in the picture.
Use the hoverboots to hover over the arrow platforms to reach an even higher speed. You will pass through several dimensions and ultimately make the long jump to the Archives.
Access the Vault of Knowledge in the Archives
As soon as you step on the first platform of the mobile Archive, you will have to face Nefarious' machines. Use all available space to dodge attacks and focus on defeating the enemies using ranged laser attacks and the new sniperbots.
Once the fights are over, reach the mechanism marked by the game to use the crank. This will bring you to the top level of the Archive, where you will find the Vault of Knowledge. Unfortunately, the new bosses - the Invasion Commanders - will prevent you from completing the mission objective.
Boss Fight - Invasion Commanders
The bosses share the same health bar, but you can try to attack them one by one to defeat one of them faster so you don't have to dodge the attacks of two enemies at the same time. The Invasion Commanders have identical main attacks to the Nefarious Destroyer you defeated in the early game. These attacks include:
- shooting blue projectiles - run to the side to avoid getting hit by enemy rocket fire. Also watch for the red marks on the roof and move away from them,
- shooting a large laser - it moves in a horizontal line. You can jump over the laser beam or just quickly move away from the bosses to get out of the weapon's range.
The bosses are also capable of jumping across great distances. Quickly move away from where they plan to land and remember to use the Phantom Dash when necessary.
Expect that later in the fight, regular enemies may also start appearing on the archive roof. You can attack them if they get in your way too much, but don't turn your back on the bosses as this will make it difficult to properly dodge their bigger attacks.
During the fight, try to look for opportunities to fire at the exposed boss cores installed on their chests. This will damage them more effectively. Whenever the commanders are positioned close to each other, you can also try to hit them with area of effect weapons such as the Lightning Rod.
Once one of the commanders dies on the battlefield, the battle will become much easier, as you will only have one main enemy to attack. To finally win, all you need to do is defeat the second machine.
If you need healing, ammo and health crates can be found in the arena.
After winning the battle, reach the crank again to power the generator. Once that's done, approach the Vault of Knowledge. A long cut-scene will play and your mission on Savali will end.
Once you return to the vicinity of the spaceship, you should talk to Mrs. Zurkon, as she has a new weapon on sale - the Void Repulser for 17500 bolts. This weapon has two main uses - you can activate a shield to protect yourself from enemy attacks (press the R2 trigger halfway down), and you can counterattack with an energy hit (press the R2 trigger all the way down) that can weaken or kill nearby enemies.
There will be two new main destinations on the planet list - Blizar Prime (Blizon Mines) and Cordelion (Kedaro Station). You may explore these locations in any order.
