Cave Chaos 2 is an action-platformer and the second 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.
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.
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 latern, 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.
