Player Experience Highlights

Community Insight:

Tons of bugs, hero become useless(cannot attack, automatically die every turn) after a world boss fight. We dont know how that happened, we use all of our resources on that hero and now quit.


Had to fully uninstall game then reinstall on update 1.3.6 works completely fine now.


Receiving error that country/location currently does not support latest update to game in the U.S. Is a fix coming.


The game is a lot of fun and is a cut above the rest of the idle genre. If you got rid of auto sort and buffed the recruit chances slightly for tickets we would rate this game five stars. Still a fun game though.


Downloaded the game and have had it installed for 24 hours now. Overall really fun and innovative. A few flaws that we see a lot of other players are experiencing is you cannot recall extremely affecting progression. We have upgraded to 100% auto collection for cache, yet sometimes it fails to collect. Needs some fine tuning tweaks but other than that great game. Would like to spend money but if we cannot progress since recall is bugged, we will hold off.


Great game, honestly Im grinding to be one of the best just because its so fun and addicting to play but theres one downside to this game that does make it a key idle game. It doesnt seem to ever register that youve exited out of the game so you can get any rewards from being away like all other idle games do. Other than that good work team.


Great game but the the decompose feature is not working. We go to different zombies and click decompose and it wont go beyond there.


We've been spent the day enjoying this game, but suddenly have lost the ability to watch ads to speed things up. We can also no longer recall to reset our progress, and level our troops. We've read in another comment that the in game support email is also broken. We would not recommend spending money on this game until these issues are resolved.


This is a fun game but has some major issues. You are supposed to be able to recall your troops which starts you back at the beginning with bonus loot. The problem is when the timer reaches zero, instead of the button lighting up and letting you recall the troops, it stays greyed out and the timer resets to 60 minutes. We tried sending an email to support through the link in the game, but the email came back as undeliverable due to the support email address being nonexistent.


Love game but for some reason we cant sign in every time we try it just gives us a zombie in a hamster wheel so frustrating.


Disable auto sort. The computer sorts weird once you get the hang of it its a neat little game. The animations scream quality. And the art style is pretty good. Satisfying gameplay plus you dont pay for zombies to merge. It keeps your fingers busy plus with the auto merge ability it give hard fingers a break. Overall we really like this game.


Its fun, more content needed but overall its fun.
