How to unlock the Extinction Event achievement in Ratchet & Clank: Rift Apart - Definitive Guide

Grunthors spawn on Sargasso. You can either take your time exploring every time you visit or you can pick one of the Grunthors you fight during your first visit and make it respawn by dying to the acid right after you kill it.
1. Explore the planet instead of following the bot to the Morts.
2 and 3. Before and after the story-related bridge.
4. During Trudi's quest Rivet will make a comment about a "big fella" and there's one in that area.
5. Late in the story, you come back and there will be one.
6. Skeletal Grunthor during one of the Bronze cup battles in Zurkie's.

2 and 3 do not respawn after killing it as they are story related.
1 does respawn, killed it 5 times and then died to acid and revisited before it popped, not sure why I had to kill it 5 times as I had killed a different one previously. I recorded my path from the morts to it, link to video of my path here: https://twitter.com/Tackytics/status/1520874373216878592?t=A... - just kill yourself in the acid nearby as stated in the guide and you will spawn back at the morts.

They keep re-spawning so this is not missable.

After the mission on Cordelion, return to Sargasso and new gruntors will spawn. You can also increase the amount on NG+.

If, after killing Grunthor, you click Return to checkpoint , Grunthor will spawn again. It worked exactly the same way with the one on the central island.

I killed 3 of these mobs at the beginning of the game for rivvit. then I killed 2 of them while flying. these two did not study. As soon as he got off it and killed two again, they immediately gave him the trophy.

I confirm ReGor94’s comment, yesterday I checked, the gruntor spawns constantly, only I didn’t reboot from the checkpoint, I just walked, jumped into the acid away from the spawn point and returned to the gruntor, so the trophy is unmissable (if it’s not a bug), I did it yesterday in 5 minutes .

One Grunthor spawns constantly. You just need to move to any other planet and back to Sargasso. I’ll also add that during the flight to Trudy and the shooting of the Gruntors with fire, they didn’t give me a trophy, but I could be wrong.
