How to unblock cave entrance in StarRupture

While exploring the Arcadia-7 map, players will encounter a small circular icon indicating that there is an underground cave entrance nearby. It is blocked by vine growth. Players may have experienced this many times and felt frustrated while trying to throw a grenade or use an extractor. Nothing seems to work.

Fortunately, the solution is much simpler than you might think. The player must wait for Rupture to erase all creatures. Once you're on the planet (including vines), head out to explore. This means that the cave will only be open for a short period of time while the effects of the burst wave pass through.

Life on Arcadia-7 regrows really quickly (in a matter of minutes), so players will need to time their cave explorations carefully. It's like a cave, because if you go underground and stay there too long, the vines will grow back and block the way out.

This also applies to the time players have to search and descend into caves, but there is a solution for this. Build a small base with a habitat near the cave and wait there for the implosion to occur. Once the plane's surface reaches an 'acceptable temperature' (according to GAL), players can leave the shelter and dive into a nearby cave.
