Collision Chaos

Next round >>

Collision Chaos is the second round in Sonic the Hedgehog CD. The boss of the third zone is a giant pinball machine operated by Dr. Robotnik. This round is where Amy Rose is captured by Metal Sonic, occurring right at the beginning of the round.


Present and Past

It is an unusual, possibly psychedelic mechanized forest with a well-established casino. Neon signs line up across the casino, which seem to be stylized Japanese writing but is actually gibberish. A lake is shown at the very bottom of the zone. In the past, many of the casino features are not present due to it still being in construction. The stage has a rather strange orange tint to the forest, as well. No signs depict the completion of the casino here; instead, airborne rocky structures replace them. The lake is also present in the past timeline.

Bad Future

The bad future features a darkened sky adorned with red clouds, and seems to be haunted with gray machines. This timeline is one of the few to remain functional and colorful while showing a dark future for any passerby at the same time. There seem to be no plants present here, and the signs are still illegible but fully functional. The lake here looks to be teeming with radioactive waste, as evidenced by its reddish-orange tint.

Good Future

The good future shows a futuristic, blue colored, inviting casino with a bright pink sky. Plants are futuristic and natural adding pleasing attractions to the "casinotopia", while the waters below are crisp and clean.

  • When accessing the game files, Collision Chaos is listed as R3 after Palmtree Panic which is listed as R1 suggesting that a round got scrapped during development.
  • In an early prototype, Metal Sonic was supposed to be able to damage the player in the beginning of Act 1, which is why there is a hidden shield at the start of the level.
  • In the Japanese version Sonic the Hedgehog CD, the music for this round (Bad Future) is later remixed in Sonic Chronicles: The Dark Brotherhood as the music for Angel Island.
  • This stage is very similar to Casino Night Zone from Sonic the Hedgehog 2. Coincidentally, both games were in development around the same time frame.
