To unlock Über Hardcore mode, you need to clear every level on Hardcore mode.
To unlock Hardcore mode, you need to clear each of 4 boss levels with at least 4 Stars while playing on the Hard difficulty setting.
On Hardcore mode you have only one life and no checkpoints. You must get through the whole level in one attempt.General tips:
- Always take available Health Pickups.
- Since you only have one life, take your time when playing through the level.
Either way, i have cleared Über-Hardcore
