This event occurs every 4 weeks, during the Alliance League. It consists of killing 40 special zombies and collecting their tissue samples. You’ll have 4 days to complete the quest.
Select your difficulty
At the beginning of the event, you can choose the difficulty of the quest. It is ranked from D to S. D being the easiest and S the hardest. You have to unlock the previous difficulties to reach the S rank.
Rewards
Of course, like every event in the game, this event will grant you rewards. The rewards are very good at the S rank, so I definitely recommend doing this event each time it’s available. You will receive the rewards at the end of the event if you can’t finish all 40 zombies; otherwise, you get the rewards when you finish the quest.
You can also get some rewards from reaching the zombies at each number multiple of 5 (5, 10, 15, 20, etc). Below, you can see the rewards you can get for reaching the 15th zombie at the S rank quest.
How to do the quest?
There’s multiple ways of doing the quest depending on the time you have available, the strength of your account and the stamina you have. Once you spawn the zombie, you’ll have 3 options available:
- Kill the zombie yourself and use 50 stamina per squad (less if you use a zombie hunter hero and if you chain the zombies)
- Rally your zombie and use 150 stamina
- Use a vaccine and let a person from your alliance to rally it.
You can obtain vaccines (with about a 30-50% chance) by joining rallies of other people’s zombies. Joining rallies will also grant extra rewards. You can get one blue tile of resource, up to 20k experience book, 15 or 30 minutes speedups and one purple tile of resources if you’re lucky. Note: You won’t receive the extra rewards if you join the rally of your own zombie! It’s a waste of 150 stamina to join the rally of your own zombie!
If you have a lot of time and stamina, the best way to do the event is to join as many rallies as possible and then use your 40 vaccines to get your zombies killed by your alliance’s members.
If you don’t have much time or stamina, you can kill as many zombies as possible by yourself, then ask for help with vaccines on the zombies you can’t kill alone.
