Zumbi Blocks - version 2.1.5.0
In this May update i'm adding a helicopter rescue sequence at the last wave, after which you beat the match and return to lobby.
Like i promissed before, now you need to beat certain modes to unlock other modes.
This is tracked through challenges, that are tied to 8 Steam Achievements. Challenges can also reward you with new skins and perks, and extra perk slots.
All improvements can be checked on the full change log below.
