Merge monsters to feed the Devourer in this idle merge game mashup!
Description (
Characters: 2197 of 4000
)
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 • Expand your lair. Unlock new equipment including; graves, altars and portals. • Attract champions, merchants and thieves to your lair. • Complete feats, master spells, brew potions. • Use a unique prestige mechanic that takes you to unexpected places. 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.}

I been playing both of your games for a while and I just love them, i'll write a review for apocalypse on it's own game. but for this one: keeps me entertained, I love the creature's words when I pick them up, and much more that I would run out of room to type, overall. I highly recommend It if your looking for a game to keep people with ahdd (like me) entertained when your offline

its a fun game thats held back a lot by all the ads and microtransactions. it would be a lot better if you could just buy the full game (with no ads and unlimited mana, slime, etc.) for a single transaction like $5 to $10. the devs are obv way too greedy considering some of the microtransactions are like $10 for something that you can play through in 10 minutes.

Эта игра настолько клевая, что я жалею, что не могу в нее задонатить из россии. Если бы была возможность отобразить часы игры, я был бы уверен, что наиграл в нее1000+ часов. Если ты читаешь этот обзор и думаешь качать ли, то дерзай не раздумывая. Почти весь донат (кроме буквально 3 вещей) ты можешь получить играя в игру, а самой всплывающей рекламы нет - только когда ты специально ее включаешь, и то, дадут тебе это сделать всего 4 раза в день для маны. Буквально меню кричит, что игра - от души

AAA mobile game. I'm not sure if they could make a better one! Could we get push notifications for when our resources are full?
