Cave Chaos 2 is an action-platformer and the second game in the Cave Chaos series, released on May 17, 2012. It retains the same gameplay as the predecessor Cave Chaos, where players control miners trying to escape a cave before it collapses. An HTML5 port was released during the time period of November 12-13, 2020[1].
The game starts with a cutscene showing the brown miner sleeping against some barrels. A puffing monster hops toward the miner, this waking him up. The brown miner approaches the monster, looking confused. Then, the puffing monster puffs out, sending the miner back, knocking over the barrels and sending him down into a cave.
The game was first hinted in a pixelled image on Nitrome's February 15 blog post. Nitromians were encouraged to guess what the mystery sequel would be.
A week and two days after the pixelly preview image release, Nitrome revealed Cave Chaos 2 as the game hinted in the image. Along with this, a full preview image of the game was revealed, displaying the sequel's polished up graphics and a new enemy unfamiliar to the first Cave Chaos.
On Thursday, April 14, Nitrome made another blog post, this time revealing an image of the miner against the silhouette of the Under-Dweller, the final boss of the game.
Most aspects of Cave Chaos 2 were the same as its predecessor, although there were some obvious changes distinguishing it from the first Cave Chaos.
Unlike earlier Nitrome sequels, the graphics in Cave Chaos 2 were noticeably different than from the first game.
In the beginning of the first level, the sign that says "Run" is wooden and held up by a bat, but in the second Cave Chaos, it is a floating white arrow.
If a miner got caught in between two rocks as they were being placed, they would shoot out vertically in the first Cave Chaos. Getting crushed between two rocks in Cave Chaos 2, however, kills the miner.
When the level begins in the first Cave Chaos, the bats will immediately start placing platforms. In the second Cave Chaos, the placing of the platforms is delayed until after the miner starts moving.
When the miner touches the end platform in the first Cave Chaos, they will automatically walk to the finish lantern, without a player's control. In the second Cave Chaos, the player must get the miner to touch the lantern rather than simply reaching the end platform.
When the player runs quickly on to a high-speed mining cart, they can get stuck in the back and still control it.
When a dynamite is on a barrel and the barrel is knocked out, the dynamite is seen in midair.
When a high-speed mining cart is left at level five, the rock underneath will fall and the the cart will float in midair. It will fall when touched by a miner.
If the player hits just appearing block, they'll be bounced backwards with high speed.
Markus Heinel's website has on the Cave Chaos 2 page of his portfolio is an unused additional ending image[2] that shows the brown miner inside the Under-Dweller's mouth [3].
In the background of some levels (such as level 4), a creature highly resembling Captain Tongue appears in the background, licking a skull.
Unlike the first Cave Chaos, Cave Chaos 2 allows players to have more than one powerup simultaneously.
Even though the art of this game is much more refined than its predecessor, both games were designed by the same artist - Markus Heinel.
Even though dynamite does not harm the player, it is able to hurt the Under-Dweller.
The "Press 'p' to continue" text seen on level 1 when the level is started can be highlighted.
This is the final Nitrome game to have a pause button, music button, and sound effects button all displayed on the same screen, as the next game, Super Snot Put, introduces the settings cog which serves as a pause button and contains both the previous sound buttons.
