Shell & Shield

Little castles. Grand sieges.

Shell & Shield is an offline 3D artillery strategy game. Build your castle, choose three favourite battle cards and face an AI opponent across a destructible battlefield.

AIM AND BREAK THROUGH

Cannons fire automatically. Take control of their aim with a touch gesture, adjust angle and power, and find a path through the enemy's defenses. Destroy the enemy core or every enemy cannon and cannon site to win.

BUILD YOUR DEFENSES

Earn gold through battles, buy and upgrade castles, and build replacement cannons on available sites. Use your battle cards to improve weapons, reinforce defenses and unlock elemental effects.

DISCOVER EACH BATTLE'S CARDS

Save three favourite cards. Each battle draws one from your choices, one from your opponent's choices and six other cards, creating a shared pool of eight. Reveal the pool before the siege and adapt your tactics to the cards in play.

GROW YOUR HERO

Earn Hero XP by playing. Develop nine skills across Builder, Gunsmith and Mage branches. Reinforce materials, improve artillery and bring healing or elemental magic into battle.

CHOOSE YOUR BATTLE

Play quick battles against the AI or progress through the campaign with three difficulty levels. Interactive training introduces aiming, cannon production and the basics of a siege.
