Core Fun

What makes it different

Familiar idle-RPG foundations, with two things you will not find elsewhere.

Heroes ride the tank

Place heroes into up to 15 slots on the tank itself. Each of the 11 tanks opens a different slot layout, so your tank choice is your strategy.

Rescue, then rebuild

Every chapter you clear frees more of the 60 captured villagers. They move into buildings you construct, and the ruined kingdom visibly comes back to life.

An idle game with an ending

Most idle games are abandoned before anything concludes. Clear the final chapter here and you get a real ending — a feast in the kingdom you rebuilt.

Eight axes of growth

Heroes, tanks, gear, pets, relics, runes, summons, and the town. Leftover shards convert into StarSoul, so nothing you earn is ever wasted.
