The final quest of the “Flashpoint” update in ARC Raiders is called “The Last Log”. Pick it up from Shani. The job is all about tracking down the researchers’ info on the Manticore, and every objective sits inside the Seed Vault. Like most quests in the game, it has to be finished in a single run. The tasks aren’t too rough, but if you’re stuck this ARC Raiders guide will get you through.
Walkthrough for “The Last Log”
It’s one of the shortest quests in the game and is set entirely around the Seed Vault in Stella Montis. You can drop in with free gear and extract via the ventilation shaft right next to the objectives. If you spawn far from the Vault, just surrender—nothing in your inventory will disappear.
There’s also a back exit from the Seed Vault in case a Shredder is camping the main door and you can’t leave the normal way.
Once you reach the Seed Vault, grab the researcher’s journal. It’s sitting just outside the entrance. Interact with the panel to tick off the first objective.
Next, find the hidden key. Head west and hang a left to spot the researcher’s clothes hanging nearby. Search them to snag the key.
Save
Key in hand, return to the Vault door and open it (unless another player already has). You’ll need a Power Cell; it spawns randomly within about 50 m of the Vault. Grab it, slot it, and the door swings open.
Head straight inside, ignoring the side bays with “Misc. Seeds” (you can trade those to Celeste later). Up ahead, open the Seed Vault crate. It drops the Official Closure Documentation you need to haul back to Shani.
