Stardust Speedway Bad Future

Stardust Speedway Bad Future is a reskin of Stardust Speedway Act 2 by Axanery, designed to make the level resemble its Bad Future Design from Sonic CD. It is also unique for featuring custom animated tiles and "readding" Eggman's laser beam from the original fight, which was absent in mania.

Features
Rather than a full on reskin, Stardust Speedway Bad Future actually ports some of the original tiles from Sonic CD. Small details, including the busted Horn objects, broken pipes, and worn out speed rails, all make a return. The Background is a darker shade of red in contrast to the neon pink in Mania, and the Metal Sonic fight features the iconic red thunderstorm travelling overhead in the background (Though the lightning itself cannot be added yet).

For objects, enemies themselves are relatively unchanged, and are mostly the same and without the cracks and signs of wear common in Bad Future Badniks. Of interest, though, is that the Propellers of the Kanabun badnik have gone from blue to dull grey, though this is less likely an artistic change and more to do with the fact that the pallete would create inconsistencies with the sprites.

By far the most significant changes are the re-addition of Robotnik and his laser beam of death during the race portion of the Metal Sonic fight and the presence of Amy Rose right before the former. Amy can be seen squirming on a pole (similar to how one finds her at the end of the zone in Sonic CD) just before the speed boost that takes you to the race with Metal Sonic. Although she is fully animated, she cannot be interacted with, and does not reappear at the end of the level, which just gives you the standard animal capsule instead. As for Robotnik, he functions similarly to the CD version, following a short deal behind Metal Sonic whilst constantly firing a deadly laser. Thankfully, though, he is in reality just a reskin of the spike wall, and therefore being hit by him will not result in an instant kill like it does in CD. It is also interesting to note that Robotnik's sprite has been changed to match his Mania design, rather than being a direct port of CD sprites like the rest of the mod. Taking down Metal Sonic will cause Robotnik to fall as well.
