Invasion!

Collector invasions occur daily and spread ten new invasion waypoints, resembling UFOs, across the map which disappear once beaten. Each one of these stages costs 5,000 food to fight and drop an invasion reward chest when won. These levels can be fought consecutively with a "Next Battle" button appearing after being won, not requiring one to scour the map. Roger provides a unique reward chest that contains a Tournament Ticket when all 10 waypoints are won, alongside the "Head of the house" daily quest is completed which gives 10 quest keys without Premium.

Enemies
There are three Invasion! enemies, one for each of the three types; a Battle Engineer and two unnamed enemies, one a warrior with two different skins resembling either a demon or a dog and a gunslinger human also with two appearances. The same three skins are used across the entire invasion.
