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 army of monsters (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 new abilities and spells.
Complete feats to unlock new stations and equipment… graves, altars, fridges and even a bathtub to hold excess slime. New stations will let you summon stronger (and even more tasty) minions. Manage your lair and monsters to maximize your resource generation.
NecroMerger is a whole new type of game that combines merge and idle mechanics with resource management to create something truly unique.
Grow Monsters
• 100+ minions to spawn and merge.
• Minions have unique abilities to manage (resource generation, damage, deliciousness).
• Create new Forgotten Minions by merging different types of minions together.
• Unlock powerful Legendary Minions with big benefits.
Expand your Lair

Events
• Take part in distinct repeatable events with special mechanics. You’ll battle your sister, keep bees and travel back in time.
• Head outside the lair to play seasonal events, whether that’s organising your own birthday party or playing Santa.
• Unlock unique skins and themes to change up your lair and its inhabitants.
Idle Merge Mashup
• A unique system of resource management.
• Resources generate even when you’re offline.
• Months of fun!
From the makers of Idle Apocalypse and Idle Mastermind, NecroMerger has the humour and inane chatter you’d expect of a Grumpy Rhino game.

advertisementsperformance_and_bugsI previously gave this game a 4 star review because I liked its art and mechanics. It is now a 1 and would be a 0 if I could because 99% of the ads restart the game and don't even give you your rewards, and then the ads go on cool down so you need to wait to try agian only to be tricked into a double ad where NEITHER of them work and restart the game again.

contentmonetizationFun game, but like any idle game you get to a standstill every now and then. The sprites are well designed and the variety of minions is cool. The interactions when you pick them up/move them are funny. You can farm for coins and gems so you don't really need to pay for anything. There are packs that can be quite helpful, though. Overall, it's a cool game and I would recommend it.

performance_and_bugsmonetizationfeature_requestsGreat game, generally I don't like idle games but this one is a lot of fun. You don't have to wait too long befor you can do more and their's different events that come and go that you can do a lot with while waiting for the main to recharge. EDIT: I'm owed 2,688 gems but no matter what route I go I can't get any response. Don't waste your time with the offerwall games, it's a scam.
