Alchemy: Merge Tower Defense

Merge Fire, Water, Earth and Air into over 40 alchemical towers, then hold the line against 30 waves of monsters. A tower defense where every merge is a discovery.

MERGE TO DISCOVER
Drag two towers together and see what the reaction brews. Fire and Water make Steam, Earth and Fire make Lava, and that's only the start: every new recipe fills a page of your Grimoire, all the way to the Philosopher's Stone.

DEFEND THE CORE
Living minerals march down the road: Cinder Nodules, armored Plated Blocks, Split Prisms that break in two, flying Sky Diamonds, Burrow Wedges and healing Vital Phials. Every map ends in a Region Lord with three phases that will make you rethink your deck. Pick your bases, equip your alchemist's bench and choose an upgrade every few waves: no two runs play the same.

IDLE PROGRESS, EVEN OFFLINE
The Lab keeps researching while the game is closed and the Alembic distills gold for hours. Come back, collect it, unlock new studies and push one wave further.
