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; speed, health, armor and range are charted on hero stats compared.

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 (11.9% of players), Zefira (22.8% of players), Bolin (16.6% of players) and Connor (10.9% of players). Ironhide’s catch-up rule makes switching cheap: a hero behind your highest-level one earns double XP until it catches up.
