Anomaly play idea.
Two portals, (or possibly more), Green and Blue, representing some plastic-bag-on-head exogenous entities presence on Earth randomly appear in play box.
The portals are indestructible for the event. Unmodded or dbl FA and TU. Perhaps hacking them has some refill/adverse effect. Doesn't matter too much.
Aim - longest links to and from these portals scores points. (Cumulative) (Allow linking under fields).
The links don't have to stay up, just be created.
Lore wise this could be to help spread the entities influence over a large area etc.
Could help balance scores, encourage creative play etc.
