StarRupture offers a lot to discover for adventurous players, but exploration can be dangerous. Underground Caves are particularly rewarding places to visit, filled with useful resources like Quartz and rare plants for crafting powerful items. They also hide valuable treasures, though getting inside can be tricky.
Found those weird vines blocking the entrance to an Underground Cave in Arcadia-7 and wondering how to get in? This guide will show you how to access these caves in StarRupture.
How To Unblock Cave Entrances in StarRupture
As you explore the Arcadia-7 map, you’ll notice small, circular icons marking entrances to Underground Caves. However, these entrances are usually covered by thick vines. Players often find this frustrating, as common methods like throwing grenades or using the Extractor simply don’t clear the vines.
The good news is, fixing this is actually quite easy. Players just need to wait for a Rupture, which will destroy all plant life – including vines – on the planet, and then they can start exploring. This also means caves are only accessible for a short time after a Rupture Wave passes.





The plants in Arcadia-7 regrow incredibly quickly, so players need to be mindful of how long they spend in the caves. If you stay underground too long, vines will rapidly block your exit, trapping you!
The time limit for exploring caves also exists, but you can work around it. Build a small base with a Habitat close to a cave and wait for a Rupture event to occur in that area. Once the surface temperature is safe – as indicated by the GAL system – you can exit your base and enter the nearby cave.
Please gather all plant samples within this cave system. They’re useful for crafting top-tier recipes and can also quickly boost your reputation with the Corporations by providing Data Points when you need them.
You can also find Quartz underground, which is a valuable resource for crafting. Collect as much as you can to get a head start on making advanced items and unlocking new recipes later in the game.




Don’t ignore the remains of the colonists who were burned – they serve as a clear warning against waiting for a Rupture to happen inside the cave. More importantly, they’re a valuable source of materials, items, and rare currencies like War Bonds, which are hard to find anywhere else.
Venture into the complex Underground Caves and you’ll find valuable rewards. But hurry – get out quickly with your team before the planet’s plants grow back and seal the entrance!
