The Wall Mustn't Fall

The Wall Mustn't Fall is about surviving waves of enemies through strategic decisions. You choose a hero with unique abilities, then defend the wall and build a team of AI-controlled allies. As the run progresses, you recruit and level up allies, equip your units with weapons and items, and shape your team's formation and synergies.

Defend the wall

Your units gain experience from kills. When they level up, they receive stat points that you can choose how to apply. You can control your hero directly, use active items and abilities, or enable autopilot to have the hero controlled automatically like your allies. Collect your loot at the end of each round.

Build your team

During shop phases, you can recruit allies, strengthen your current units, buy weapons and items, distribute weapons and relics, and choose your team's formation to make use of its synergies and abilities. You can also upgrade the shop and castle. Buying more copies of the same ally or using an item or perk that grants experience can level up an ally, giving them stat bonuses and a new ability. Having a certain number of units from the same class grants synergy bonuses.

Weapons and upgrades

Any unit can equip any weapon, though some weapons may suit particular units better. Weapons gain additional effects as the run progresses, and you can spend gold at the anvil to apply effects to them. Currency earned during a run can also unlock permanent upgrades; there are currently 89.

Sacrifice

Beating the game presents new challenges.
