Few Spears
15 waves held, at most 12 soldiers at once.
"Waves held" is a clock, not a score: the first wave is due at tick 1,200 and one more every 640 ticks, beaten or not, so wave 15 is due at tick 10,160 (28:13). The soldier limit is a peak: 13 soldiers alive at any one moment of the run ends the attempt, even if they die at once.
Why not just set an Army cap?
By hand you can: Orders → Army cap to 12 or lower before your first Barracks trains anyone. With the autopilot at the wheel you cannot: it rewrites every order each tick and recruits without a cap. So the recorded run leaves the autopilot to build and pulls down every Barracks foundation it lays. No Barracks, no soldiers: only its line trains them. The Watchtowers hold the line.
The run, in order

The recorded run
One game on seed 7 from a fresh profile, played by the game's autopilot (F1) at ×8, with each new Barracks foundation pulled down with the pointer and X. The run is left from the pause menu once the achievement is announced, and the video ends on the in-game Achievements screen. The badge on every frame says so; the game's own music, no commentary.
What goes wrong
- A Barracks finished for a moment starts recruiting; soldiers are cheap and come fast.
- With no army, no lair is ever broken, so no lair goes quiet: this route earns Few Spears, not the lair achievements.
- The holding can fall. The recorded seed held; on a harsher fen, build more towers by hand or set the Army cap by hand without the autopilot.
