Irongate: Tower Defense

Defend your castle, send an army and outthink your opponent. Battle the bot, challenge a friend or team up to hold the gates together.

Enter Irongate, a tower defence battlefield where every coin can strengthen your defences or fuel your next attack.

BUILD YOUR DEFENCE Combine Arrow, Cannon, Frost, Tesla and Poison towers. Upgrade through four levels and choose specialised branches to shape your strategy.

TAKE THE FIGHT ACROSS THE RIVER Send creeps into enemy territory to pressure your opponent and grow your income. Balance spending on your army with protecting your own castle.

PLAY YOUR WAY Practise offline against the bot with Easy, Medium and Hard difficulty. Find an online opponent with Quick Match or invite a friend using a four-letter room code.

DEFEND TOGETHER Switch to co-op and share a castle. Cover both gates and work together against incoming waves.

CHOOSE YOUR BATTLEFIELD Explore four versus maps and three co-op maps, each with different routes and opportunities for tower placement.
