Looking through all-time highest rated Switch games on deku deals I noticed Underhero is available in a bundle for cheaper than it ever has been alone.
Underhero is rated 86 on Metacritic.
All time lowest individual price is $11.47, this bundle is $9.22
The bundle includes:
I should point out one annoyance: I'm pretty sure this and similar bundles are seen as one game by the switch, so only one game icon, etc, meaning your console wouldn't recognise e.g. if you tried to buy Underhero separately.
This is different from say the Metro Redux collection where games were recognised individually
