Kingdom Rush 6 heroes

Kingdom Rush 6: Genesis TD has 12 heroes and you take 2 into a stage. On Steam each one unlocks at a star count; on iPhone and Android, 8 of them are sold instead. Here they are in the order Steam unlocks them.

Hero	How it fights	Steam unlock	Mobile
Gerald Time Saviour	Melee · Physical damage	Available from the start	Free, same stars
Zefira Battlemage	Melee and ranged · Physical (melee) and magic (ranged) damage	1	Free, same stars
Bolin Sharpshooter	Melee and ranged · Physical damage	11	Free, same stars
Connor Templar Champion	Melee · Physical damage	20	Free, same stars
Malik Unchained	Melee · Physical damage	28	Paid
Rhodes Earth Bastion	Melee · Physical damage	40	Paid
Gemina Arcane Illusionist	Melee and ranged · Physical (melee) and magic (ranged) damage	54	Paid
Ignus Flame Prodigy	Melee · True damage	58	Paid
Illiana Dragon Tamer	Melee and ranged · Physical damage	66	Paid
Oni Vengeful Hunter	Melee · Physical damage	70	Paid
Drakkan	Ranged, flying · Magic damage	76 or 80	Paid
Ashbite Red Dragon	Ranged, flying · Physical damage	80 or 84	Paid

The XP and star planner turns these star prices into a route: enter how many stars you have and it lists what unlocks next. Drakkan and Ashbite are listed with two prices because the published figures disagree.

Levelling them

Every hero has its own level and upgrade tree, separate from the global tower upgrades. 4 heroes have a Steam achievement for reaching level 10: Gerald (4.9% of players), Zefira (10.2% of players), Bolin (6.6% of players) and Connor (4.3% of players). Ironhide’s catch-up rule makes switching cheap: a hero behind your highest-level one earns double XP until it catches up.
