Selected seasonSeason 2: Furnace and heat planning are supported.
Only placed and verified footprints are validated. Custom measurements and world-map objectives require manual confirmation.
1. Build the fixed core
- Select the correct season at the top of the planner.
- In Season 2, place the Alliance Furnace first to establish the 39×39 heat area. Other seasons do not use this heat constraint. Place an Alliance Center if you want to center the new hive around it; its in-game radius is not inferred.
- Place Marshall Guard only if you want MG-centered population or MG efficiency statistics, then place R5, R4 bases, Cities, or other fixed structures you already know you want to preserve.
- Use Edit to select, move, rename, or place structures. Use Navigate when you only want to pan safely without moving anything.
- On mobile, selecting a structure from Add automatically uses a closer Placement View when the hive core already exists.
Planner note: The 39×39 Season 2 heat area is based on in-game observations used by the planner, not an in-game configuration table.
2. Populate members
- In Season 2, place exactly one Alliance Furnace before Populate; Heat Only requires its 39×39 heat area. In Base and Seasons 1, 3, 4, 5 and 6, use the full board without a Furnace and choose Board center, Alliance Center, or Marshall Guard as your population anchor.
- Place all R5, R4, and other structures that must stay fixed before population.
- Open More → Populate Members and choose the total player-base target. For a full alliance, use 100.
- Choose Center-outward or Square / Grid. Square / Grid fills compact rows and columns around the chosen center while leaving already placed structures untouched.
- Tap Preview. The planner shows the selected placement area (Furnace heat zone in S2 Heat Only; full 60×60 board otherwise).
What Populate does: Center-outward fills valid 3×3 regular-member slots outward from the selected center; Square / Grid fills a compact rectangular formation around it: Furnace in S2 by default, or the selected board midpoint, Alliance Center, or Marshall Guard in other seasons. Proposed bases stay on the established 3×3 lattice, inside the selected area, and clear of overlaps.
Populate never moves your existing R5, R4, Marshall Guard, Furnace, City, or other manually placed structures.
3. Adjust the preview
- Review the blue proposed member bases before applying them.
- Tap Adjust if you want to move a few proposed bases manually.
- Drag a proposed base to another valid 3×3 slot. Invalid positions are rejected automatically.
- Adjusted preview bases receive a gold outline.
- Tap Apply only when the preview looks correct.
4. check the hive
Open More → Check Hive after the layout is applied. The planner checks:

MG packingEfficiency score
MG Efficiency is available only when exactly one Marshall Guard is placed. A 100% score means no valid rearrangement of regular-member bases can lower their average center-to-center distance to that Guard while keeping the current fixed structures, alignment, and active Season 2 heat constraints.
Player names
Select an R5, R4, or regular Member base to optionally add the player's name. Names are organization metadata only; they do not change the 3×3 footprint, placement, Populate logic, or check.

🟥 Warning
- MG distance is geometric center-to-center planner distance. It is not claimed to be the game’s exact march-time formula.
- The planner does not move bases in Last War. Use it to plan the hive, then reproduce the approved layout in-game.
