Campaign Walkthrough: All 50 Levels
A stage-by-stage walkthrough for the 50-level campaign in We March as One: what each act tests, where the difficulty spikes, and how to prepare.
The We March as One campaign runs to level 50. That number matters because the game's achievements are pinned to it: level 5, level 10, level 20, level 30, level 40 and level 50 are all checkpoints, and the city levels sit on every tenth level.
This walkthrough is organised by act rather than by individual level, because the game's difficulty is structured in acts. Each act introduces a map type or an enemy behaviour, and each act has a wall where the previous act's habits stop working.
Act 1 — Levels 1 to 10: the tutorial that is not labelled
Act 1 teaches the interface. Early levels are shape against shape on open ground, and the enemy formations are simple enough that almost any painted army wins.
What Act 1 actually teaches:
- Painting — brush size, undo, and how coverage maps to fighting strength.
- Orders — the difference between advancing into an enemy and letting one come to you.
- The economy — that losing still pays, and that replaying a level for a better rating is the fastest way to grow.
Where it gets hard: level 10, the first city level. Players arrive with a broad, shallow army built for open fields and discover that walls and lanes make width useless. The fix is the first real composition lesson in the game: narrow the front, deepen the ranks, and attack through one breach.
Act 1 achievements: First Steps (win level 5), Key to the City (win level 10), Mastered (DECISIVE and HEROIC on the same level), Sacked (a DECISIVE on any city level).
The ratings you earn in Act 1 fund everything after it. A player who leaves Act 1 with HEROIC clears on the first ten levels starts Act 2 with a materially larger army than one who scraped through.
Act 2 — Levels 11 to 20: unit variety arrives
Act 2 is where the palette fills out. By this point you own enough shapes that composition becomes a real decision, and the levels start demanding specific answers.
Patterns to expect:
- Enemy formations with a refused flank — you need a wedge rather than a line.
- Levels with a river or bridge — the first places where rhombi earn their cost.
- Longer battles — the enemy has enough depth that a single exchange does not decide it.
Where it gets hard: level 20, the second city level, which is usually the first level that punishes an over-upgraded but poorly composed army. If you have been buying nodes that do not match your shapes, this is where it shows.
Act 2 achievements: Man-at-Arms (DECISIVE and HEROIC on all of levels 1–10), Knight (the same for 11–20), Combined Arms (win with five unit types).
Act 3 — Levels 21 to 30: the horde act
Act 3 introduces the horde fights the game is built around. Enemy counts climb sharply, waves arrive in sequence, and formations that worked in Acts 1 and 2 get eaten along their whole width.
The three habits that carry this act:
- Find the choke point on every map before painting.
- Narrow the front and deepen the ranks.
- Hold rather than march, unless the level forces you forward.
Where it gets hard: level 30, the third city level, which combines fortifications with horde numbers. This is the act's real exam, and it is where the city and boss level guide→ starts to matter more than general composition advice.
Act 3 achievements: No Turning Back (win level 20), Over the Hill (win level 30), Studied (half the upgrade tree).

Act 4 — Levels 31 to 40: the composition exam
Act 4 assumes you can do everything the game has taught and starts combining it. Levels mix open ground with corridors, hordes with fortifications, and timers with defensive objectives.
What changes:
- Maps get longer. A single battle can run through several waves with no chance to repaint.
- Enemy composition gets mixed. Pure hordes give way to hordes with a hard core, which means triangles have to be positioned, not just owned.
- Gold costs rise. Tier III upgrades start competing with unit purchases for the same gold.
Where it gets hard: level 40, the fourth city level. By this point the campaign expects a complete army: depth, a damage core, an anchor, and a King placed correctly.
Act 4 achievements: The Long March (win level 40), Hundred Thousand (defeat 100,000 enemies outside Sandbox), Full Roster (unlock every unit).
Act 5 — Levels 41 to 50: the last ten
The final act is short and sharp. Levels 41 to 49 are variations on everything the campaign has already asked, at a higher intensity. Level 50 is the finale, and it is the level the We March as One achievement is named after.
Preparation checklist before pushing into Act 5:
- Army size at or near the cap. If you are still short of units, replay for ratings now rather than later.
- Upgrade tree at least half complete. Studied-tier coverage is the realistic baseline for level 50.
- A formation you trust. Do not arrive at the finale still experimenting with shapes you have not used.
- The King habit. If you have not been crowning a circle every battle, start now — the aura is worth more in the long fights than in the short ones.
Act 5 achievements: We March as One (win level 50), A Million Shapes (defeat 1,000,000 enemies), Every Last Leaf (the whole tree), One of a Kind (win a level 10+ with a single unit type).
Level 50 rewards a formation you have already proven. If you want to experiment with a single-shape army for One of a Kind, do it on a level you can replay, not on the finale.
Official source: Steam global achievement stats ↗ — We March as One for completing level 50 is unlocked by roughly 6% of players, while First Steps for level 5 is above 84%, which shows where most runs stop.
A realistic time budget
Players who finish the campaign report around ten hours for 100% completion, which includes replaying levels for ratings. A straight push to level 50 with average ratings is shorter, but it will stall at the act walls — the ten hours is the honest number for a comfortable run.
