Head to the Core

"Drek hired some elite bounty hunters. Defeat them and get to Gadgetron."

- Mission description

Head to the Core is a mission in Ratchet & Clank (2016 game) taking place in the Deplanetizer. After Ratchet and Clank used the Hologuise to sneak through to locate the gravity stabilizer, they also disabled all sanitation fields. The two then fought their way through the Deplanetizer to reach the core, and disconnect the gravity stabilizer, completing Elaris' plan.

Walkthrough
At this point, the Hologuise will no longer fool enemies, so you will have to rely on pure combat. Head to the end of the room and use the vendor to refill ammo, then proceed through to the next room. Rather than heading up the grav-ramp on the left, defeat the warbots and versa-targets drop, allowing you to use the Swingshot to cross them. Proceed through the linear path to another room full of warbots. Destroy the warbots and the robomutt reinforcements (consider using the Sheepinator against the robomutts, as it will clear them quickly, and other ranged weapons against the warbots). A door will open, with blarg space commandos and blarg elite commandos heading from it. Defeat them and head through the corridor through this door.

This corrdior is filled with enemies; clear them out to reach the large room with more enemies. Fight through here to the middle, to see the bridge is out. H right to the bolt crank, and turn it to extend the bridge across. Before you cross, head left, and on a level platform above are two blarg bombthrowers. Climb the boxes stacked to head up and defeat them. From here, you can choose to use the turret to defeat remaining enemies, or simply use your weapons if you have more to upgrade. Either way, kill the warbots and a blarg dropship will appear. Destroy it, along with the other warbots that arrive, and on far right at the end of the room is an elevated platform with two more blarg bombthrowers. Climb the two stacked boxes and head on top of the platform to obtain the final RYNO holocard, which will complete the set if you obtained all other RYNO holocards.

A door will then open with a vendor and two warbots; kill them and the mission "Disable the Gravity Stablizer" will commence. A teleporter will activate, allowing you to return to your ship. Before you begin the next mission, return to your ship, and if you have not already, collect all RYNO holocards. Then, return to Rilgar and complete "Bring all RYNO holocards to dealer" to obtain the RYNO, the most powerful weapon in the game. Return here again.
