Vicious Void is a DLC [downloadable content] world in Astro Bot added in February 2025. It's another world that contains 5 Network Speed Run-styled levels and is considered to be harder than Stellar Speedway. However due to the difficulty, you don't need to race against any target time to unlock the VIP Bot in each level, similarly to the Lost Void levels.
There are five levels in Vicious Void, each one based on one of Astro's powerups.
Tick-Tock Shock, based on the Time-Stopper
Thrust or Bust, based on Barkster the Bulldog Booster
Cock-a-Doodle Doom, based on the Chicken rocket
Hard to Bear, based on the Bear power-up
Armored Hardcore, based on the Muteki
