Intrusion

Frame · Threat and upheaval situational

Something foreign intrudes into an area – from outside, uninvited, overpowering or creeping.

Design question – In your game something foreign intrudes into a known world. What comes – and what does the world lose through the intrusion?

Reference example – Plants vs. Zombies: the zombies come across the lawn, row by row. Spirit Island: invaders push into the land of the spirits and change everything.
