The Mountain Fortress Walkthrough (Demo Mission)

Last checked: 2026-10-28

Demo military mission: hold a mountain castle through a series of sieges. Wall layout, tower placement and the AI behaviours to exploit.

The mission

A pure siege-defence: your castle sits in mountain terrain and enemy waves assault it in sequence. It is the demo's showcase of the war side of the game.

Defence principles from demo footage

Wave pressure

Waves escalate across the mission; footage of "impregnable" defences shows the winning pattern is economy-to-tower reinvestment between waves, not a fixed build.

Reconstructed from public demo playthroughs and community reports (Oct 2026 builds). Demo balance is subject to change.
