Well, I'd gotten to the Vermillius Gap, I was wearing a whole ton of unique schematic gear, decide to follow the next path that leads north.. The my sandbuggy jumped a dune, landed me in quicksand which I hadn't realised was a thing there, and as I'm trying to get the bike out a Sandworm eat me.
Everything gone.
Then spent a couple of hours doing the grind to re-equip myself and build a new Sandbike, decide to head in a slightly different direction, carefully avoid some drumsand.. and then 3 sandworms pretty much dogpile me. Found myself being chased by one, then a second emerged in the ground ahead of me, and as I start to turn to run for another area.. the third freaking sandworm crests a dune and landed on me.
One more unto the re-equip grind. Solo play is definitely a touch longer...
