Alliance Tower Defense modes
Five difficulties, each with its own badge and coin reward. Clear each one once for the badge, then farm the one that pays best for your team — Insane is the only mode that also drops a Scientist Crate.
1
Easy mode
The starter mode. Learn placement here with Speaker Man and your first pulls.
1 enemy track · badge 「Beat Easy Mode!」
100 coins
2
Medium mode
For players who have the gist of the game. Bring an AOE unit like TV Man.
1 enemy track · badge 「Beat Medium Mode!」
275 coins
3
Hard mode
Two enemy tracks — built for squads. Possible solo with strong Epics, but bring a friend.
2 enemy tracks · badge 「Beat Hard Mode!」
500 coins
4
Insane mode
Pro difficulty on a single path. The Scientist Crate makes it the best farm for crate units.
1 enemy track · badge 「Beat Insane Mode!」
850 coins + 1 Scientist Crate
5
Crazy mode
The hardest mode in the game — the community wiki does not document its reward yet. Added in the August 26 update.
Reward not documented
Which mode should you farm?
Coins buy summon rolls, so farm the hardest mode you can clear reliably. A failed run pays nothing — a smooth Medium clear beats a coinless Hard attempt. Once your team clears Insane consistently, it becomes the best loop in the game: 850 coins plus a crate per win.
