01//The route
Every tower reroutes them.
Ground Machines take the shortest open route to your Firewall and re-plan around every tower you build. Bend the
route through the choke point, but you can never seal it.

Open Field // Route sim
A 9 × 13 cut of Open Field, routed with the game’s own pathfinding rules. The full battlefield is 12 × 20.
Choke Point // Live
In the game: banks of towers bend the route into a switchback that runs straight through the live choke point.
