Boss Strike 15: Infected Troops

Overview
Infected Troops is the fifteenth Boss Strike event, featuring Infected units scaled to each player's level.

This event also introduced one more unique Infected units. The Apex Bullfrog, Apex Stalker and the Apex Colossus reappeared as a reward during the event. These Infected units were rewarded for completing a certain amount of Tiers during the Boss Strike.

Players had the option to either donate or "FIGHT!" 3-5 wave formations made up of enemy units, with both options yielding a considerate amount of Boss Points that would be added to the guild's Tier pool.

During this Boss Strike, all units take extra damage through the new status effect Plague. However, all Vehicles, Zombie Hunters, Infected units, and most Aircraft received immunity to the Plague.
