Minefield

Prepare the route before the rush arrives

Minefield turns an expected approach into a trap. Place a mine around the fortress perimeter during Attack, then let an approaching infected trigger it.

How to use it

Tap MINE when ready to reveal the marked perimeter sockets. Choose an available socket along a threatened route. Tap MINE again before placement if you want to cancel.

When it helps

A fast enemy approaches with a group close behind. Place the mine ahead of them while you still have time. The blast damages nearby infected and briefly stuns affected survivors, creating an opening for your towers.

An armed mine waits until it triggers. A quiet route can leave it unused, so pay attention to where the next attack is going.

Limits to remember

Mines use marked outer-perimeter sockets and cannot be placed anywhere on the tower board. Their blast is local, so other sectors still need coverage.

The hovering Support Caster avoids Mines. Choose another response for an airborne threat.

Growing your support

Minefield Research strengthens the trap as you progress. Explore its upgrades in the game.

Try this

Watch whether the brief pause gives your towers time to finish a group. Compare a crowded route with an empty one before placing the next mine.
