Volcana is one of two second areas, being mutually exclusive with The Jungle. It is similar to the fifth world of the original Spelunky, Hell, being filled with lava and fire, although with new a new theme of industrial mining.
Although the enemies there seem much less dangerous than those found in The Jungle, the lava found all over could easily end a player's run by blocking off important passageways. Here, players can find their way to Vlad's Castle, and exit the area to Olmec's Lair.
Volcana is a fiery, mechanical world, housing many things that are either on fire, create fire, or explode. It has small lava pools with falling platforms, chains hanging from the ceiling, with Fire Bugs on them, and Powder Boxes in the walls, which will explode on contact with anything.
Most of these hazards are relatively easy to avoid, with one major exception: Lava, which can easily softlock the player by blocking the way forward from explosions in the area or from being spit by powerful Lavamanders.
Because of this, care should be taken when using bombs in Volcana because lava may spill out of pools and block the most convenient route to the exit. Although lava will disappear when it reaches the exit, this takes a long time, increasing the risk of being trapped by the Ghost.
Players carrying a flammable pack item with them, such as the Jetpack, Hoverpack, or Powerpack are extremely susceptible to a sudden demise, as many of the fire-based enemies in this area are likely to ignite the pack on a player, exploding it.
2-1: Van Horsing, Sparrow
In 2-1, the player will always find a chunk containing a locked door and a chunk containing the entrance to a cave containing a silver key. If the player unlocks the locked door, they will find Van Horsing inside, who will thank the player and toss them a Diamond for freeing them.
2-2, 2-3, 2-4: Moon Challenge, Vlad's Castle
The Moon Challenge will always spawn on 2-2, 2-3, or 2-4, but never on the same level as Vlad's Castle. It is hosted by Tun, and has an entry fee of $10,000. Here, the player can collect loot and obtain Hou Yi's Bow, a necessary item needed to reach the Cosmic Ocean.
Vlad's Castle can be found in 2-2, 2-3, or 2-4. It will never spawn on the same level that the Moon Challenge did. It is most easily accessed by activating and descending down the chain of the Big Drill, which spawns on the same level, with the Udjat Eye. The player can obtain the Crown, defeat Vlad with the help of Van Horsing, and obtain the powerful Vlad's Cape here.
