Match the build to the problem
| Stage | Choose it when | Tradeoff to test |
|---|---|---|
| Starter | You need a readable first build | Quick perimeter check; little fallback depth |
| Mid-game | The outer footprint is working | More depth; more access to maintain |
| Boss-ready | You need a second position | Keep the actual approach visible |
| Offline-ready | You are leaving active defense | Check without your character attacking |
| Co-op | Friends are changing the base | Agree who edits access and who watches |
Starter: create a small shelter/defended footprint with a clear way in and out. Its strength is seeing missing pieces quickly; its limit is little fallback depth. Test whether the first approach reaches you through an avoidable gap.
Mid-game: add a separate inner position after the starter footprint works. Its strength is another place to respond after an outer breach; its cost is more pieces and more movement to check. Test whether the two positions are both reachable and useful.
Boss-ready: keep an observed approach visible, preserve an alternative position, and place defenses so losing one exposed part does not remove every useful attack position. Test the ordinary wave setup first; boss attacks and targeting may differ.
Offline-ready: remove dependence on your character standing in a particular spot. Finish walls and check equipment access/coverage before leaving. This is a design test, not proof of offline damage, income or survival limits.
Co-op: divide geometry changes and approach watching between people. A second builder should not silently open another entrance. Six is the server limit, not a verified editor count.
A worked improvement
Suppose your wide base has an unfinished corner and you cannot tell whether stronger equipment is needed. Close or shrink that unfinished corner first, using parts you already have. Retry from a comparable wave/state. If the entry changes, the structural edit helped; if the same enemy now reaches a different gap, inspect the perimeter again. If no gap remains but attacks fail to cover the approach, examine equipment placement. This separates geometry from spending without pretending to compute efficiency.
More height and walls are not automatic upgrades
An elevated position may improve your view, but can isolate you from another section. Extra layers may offer fallback space, but can block movement or equipment. A narrow lane may be easier to watch, but is only useful if enemies actually use it; do not assume walls force a path. Keep a route back and watch the next wave before committing to an elaborate maze.
Upgrade in a readable order
Finish the baseline; fix the first repeated failure; add fallback depth; recheck coverage/access; then expand. Keep a simple note of wave/state and what failed first. Do not compare a boosted boss run with an earlier unboosted starter wave as if the layout alone caused the difference. See base layouts for the placement order and boss guide for the preparation audit.
