Hey, all. So, I recently went back to retry Hunter Story 2 (an entertaining game, made by Tukkun from Crovy’s HunterStory). Unfortunately, the forum that used to have the info on how to get the secret bows has died, and I’m at a loss. If anybody can find any info, I’d be grateful, and if not, I’ll post whatever I discover (if anything) so that future versions of me can google for it >_>
EDIT: Just got access to the secret bows, but it’ll be a while before I can start unlocking any more :P
Rain Bow: Unknown; unlocked for me immediately after buying Golden Bow.
Mega Ultimate Bow: Available for 121,500,000 in the shop.
