Booster Pack Heroes

Booster Pack Heroes mixes card pack opening with tower defense. You tear open packs to pull heroes and spells, then put them to work guarding a tower against waves of monsters that keep coming. Each pack type has its own pool of cards, and some cards are rare, so part of the fun is chasing the pulls you want. Surviving earns Mastery, which you spend to upgrade your heroes and spells and unlock new abilities. The waves get more dangerous the longer you hold out, but what you earn carries into the next run and lets you last a little longer each time. The game is split into chapters. Beating a chapter's boss unlocks new packs, heroes, spells and challenges, and later you travel to other realms with their own secrets. It's a short incremental by the developer zup, planned for Steam on November 10, 2026. It suits players who like collecting cards and watching a defense get stronger from run to run.
