Collision Chaos is the second round from the game Sonic the Hedgehog CD. It follows Palmtree Panic and precedes Tidal Tempest.
It is an unusual, possibly psychadelic, mechanized forest with a well established casino. Casino signs line up across the casino which seem to be japanese writing but may actually be illiterate. A lake is shown at the very bottom of the zone. In the past, many casino features are not present, due to the casino still in construction, and the stage has a rather strange orange tint to the forest. No signs depict the completion of the casino, but rather airborne rocky structures replace them. The lake is also present in the past timeline. The bad future is darkened by the sky and seems to be haunted with grey mechanisms. This timelne is one of the few to remain functional and colorful while showing a dark future for any passerby at the same time. There seems to be no plants present here, and the signs are still illiterate but fully functional. Also, the lake here looks as if it was teeming with radioactive waste. 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.
Nearer to the beginning of the level, as Amy Rose is following Sonic, Metal Sonic rushes in and kidnaps her, disappearing as quickly as he came.

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.
