- Back to: Sonic the Hedgehog CD (prototype 510)/Comparisons.
Similarly to Palmtree Panic, Collision Chaos is mostly complete, save for some layout changes. Some objects don't work as intended and the missing sound effects are noticeable, but to the untrained eye it appears to be very similar to the final game.
Act 1
When Metal Sonic captures Amy, the spikes he blasts through are pointing upwards, rather than sideways.
Sonic doesn't automatically curl up when entering tubes. It's a common sight in older prototypes.
In the past, the water at the bottom of the stage is reflecting the orange sky. The final game turns this colour to pink, even though it doesn't make much sense.
The prototype is littered with these objects, which capture Sonic for a few seconds without awarding him any points. They still exist in the final, but there are less of them, and they add to Sonic's score.
In the final game, these springs send Sonic in all sorts of directions. Here, they're all pointed upwards.

Act 2
In the final game, these bouncy "glass" objects make a smashing sound. Here, they just disappear when touched.

Eggman takes a little longer to escape once defeated. You're left for a few seconds in limbo as he climbs out.

The flowers in the 510 prototype are unique to each zone.
