The Lava Cave is a new, carefully crafted and well-balanced monument. It combines natural hazards, intense combat with scientists, resource gathering, and valuable loot.

Deep underground lies a deadly lava cave that flows seamlessly into a fortified bunker. This monument is meticulously designed: balance, atmosphere, and attention to detail make it not just a challenge, but a true adventure into the depths of the earth.

To access the bunker, survivors must traverse the scorching lava cave, navigating light parkour elements above pools of molten magma. Inside the cave, valuable ore spawners and loot can be found along the way, as well as medical crates to help players survive longer. After this, two scientists block the path — eliminate them to proceed further.

The next step requires activating the red keycard. This opens a room containing an elevator that leads down to the lower levels of the bunker.

Escaping is not easy. The monument cannot be exited without activating the green keycard. To do so, players must defeat a significant number of both regular and heavy scientists. The green keycard powers the backup generator, activates the fire elevator, opens its doors, and turns on a green guidance light to help navigate the underground corridors. The generator lasts for 5 minutes.

During this time, players must fight their way through the lower levels, ride the elevator back up, defeat two heavy scientists, collect the loot from the main room, and finally leave the monument in one of two ways:

-- through the ancient catacombs hidden deep underground

-- via a shorter exit back into the lava cave
