Store description
The Devourer is always hungry and it’s your job to feed it in this idle merge game mashup. Play as the NecroMerger and use dark magic to summon an array of creatures (skeletons, zombies, demons, banshees… the list goes on). Merge them from piddly little grunts into massive (and tasty) brutes, before feeding them to your ever hungry pet.
As you grow your Devourer you’ll attract the attention of merchants, champions and even rivals. Some can be useful, others must be fought… or fed to your insatiable pet. The bigger the Devourer grows the more your lair will expand and you’ll unlock powerful abilities and spells.
Complete tasks to unlock new stations and equipment… graves, altars, fridges and even a bathtub to hold excess slime. New stations will let you summon new, stronger (and even more tasty) creatures. Manage your lair and your underlings to maximize your resource generation.
NecroMerger is a whole new type of game, which combines merge and idle mechanics with resource management to create something truly unique.
