Before you descend
A few things to know.
What kind of game is Bonecaller?
A single-player idle auto-battler. Battles resolve automatically; choosing, strengthening, and arranging your undead Host drives your progress.
Does progression continue while I am away?
Yes. The offline bank simulates up to twelve hours of eligible progress. Named boss encounters wait for your return. Read how offline progress works.
Is Bonecaller available now?
Yes. The full Windows alpha is free on itch.io. Choose Download Now, then No thanks, just take me to the downloads. Steam publishing remains pending.
Which platforms are planned first?
Windows PC is live now on itch.io. Android is now the first mobile target, with iPhone planned after mobile UI, testing, and store review are stable.
What does the free download include?
The full current Windows alpha, including its progression systems. Donations are optional and give no gameplay advantage. Bonecaller remains in development, so balance, presentation, and save compatibility may change.
Is there a battle pass?
The Charter is a permanent cosmetic reward track. In v0.1.9, everyone can equip Bone-Snow weather and earn Ash-Wind through Pantheon play. Open Settings, then Weather Wardrobe & Rewards. The supporter lane is preview-only and is not for sale. Your earned progress does not expire. Donations do not buy a pass or future features.
What if I already bought Bonecaller?
Existing itch.io owners keep access to updates. Previous paid buyers will receive the first supporter pack at no additional charge when it becomes available.
Are there paid random rewards?
No paid gacha or loot boxes are part of the current game. Recruiting and ordinary reward drops happen through play.
