Maze-building defense
Defenses obstruct movement as well as attack. Enemies follow a remaining reachable route, so path length and coverage increase tower exposure time.
The player's decision
Spend on a longer route or more damage along a shorter one?
Original scenario
Original setup: four walls on a six-by-six map. A long detour outside range loses to a shorter bend that passes the tower twice.
Start with this prototype
Build six-by-six with four walls and one fixed tower. Preview path/range and reject complete blockage explicitly. Stop a fixed wave, allow wall removal, and omit flying enemies.
Change one variable
Track total and in-range path lengths rather than rewarding uncovered detours.
What to observe in a playtest
Does a blocked placement preserve budget? Do routes and targeting update after wall removal?

Original analysis · version 1
Common pitfall
Check every entrance after edits. Repath existing enemies from current positions without teleporting.
Observations and sources
Cases refer to public documentation. Developers and community wikis are credited separately; document review is not a claim of hands-on testing.
- Defense Grid: The Awakening
Open areas and fixed roads combine with line-of-sight and ballistic placement tradeoffs.
- Sanctum 2
The building phase explicitly uses walls and mazes before defending the cores.
