Description by ReferenceNull Written by the developer, not by AppBrain. Click to read.
Build your own monsters, piece by piece, and watch them fight.

In MoltKeeper every enemy you beat drops samples of the parts it was wearing. Collect enough and that part is yours: research it, bolt it onto your creatures and take on something bigger. The tougher the fight, the better the loot.

BUILD SOMETHING WEIRD
Start with a body, then fill it with jaws, eyes, claws, tails, wings and a glowing core. Every part changes how your creature fights, so a tanky wall, a sneaky skirmisher and a long-range lobber can all start from the same body. Swap things around whenever you like.

SET UP, THEN SIT BACK
Place your squad and let the battle play out. Get your matchups right with elements and roles, then fire off a creature's core burst at just the right moment. Fights are quick, so one more stage is always easy.

GROW YOUR CREATURES
Level them up, Molt them into stronger forms and upgrade their parts all the way to five stars. Every Molt opens new sockets and makes room for wilder builds.

HUNT RARE MUTATIONS
Some parts never show up in the campaign. Track down the wild creatures carrying them and claim them for yourself.

TAKE ON OTHER KEEPERS
Send a copy of your best creature into the Wilds, where it shows up in other players' battles while you're away. Check back to see who it beat and what it brought home. In Rivals your own creatures attack other keepers' defenses every day, while you set up the defense they have to beat. Climb the weekly boards and fill the Renown season track with new looks.

FRIENDS, CLANS AND DUELS
Add friends, see their keeper cards and compare Keeper Power on the boards. Found or join a clan and take on the weekly clan hunt together. Challenge a friend to a duel: you both place your creatures blind, then watch the fight play out. Duel invites reach your phone even when the game is closed.

EXPEDITIONS AND THE DEEP
Send creatures off on expeditions to gather loot while you're offline. When you've beaten the campaign, dive into the Deep: tougher and tougher floors that start fresh every week, guarded by Deep Lords and stuffed with parts you can't find anywhere else.

PLAY YOUR WAY
Quick sessions or long ones, it's up to you. Timers keep running when the game is closed, and your phone can let you know when something's ready.

FAIR TO PLAY
MoltKeeper is free to play. Amber speeds things up and unlocks cosmetics, but looks never change a fight. Ads are optional and stay off unless you switch them on.

8 chapters, 200 stages and nearly 100 parts to collect. Play on your phone or PC with the same account.
