About Invasion of monsters: Don't let the monsters pass!: Defend Your Base from Monster Waves

Invasion of monsters: Don't let the monsters pass! puts you in charge of a base under relentless assault from waves of mindless monsters. The core challenge is straightforward and urgent: stop every wave before the monsters break through. To do that, you build turrets, walls, and traps across the map, and establish a bank to accumulate the resources that keep your defenses growing.

How to Play Invasion of monsters: Don't let the monsters pass!: Build Turrets, Walls, and Traps

The goal is to place and upgrade defensive structures — turrets, walls, traps, and a resource bank — strategically across the map to hold back each monster wave. Select any item from the store, position it anywhere on the map, and then revisit the store icon to upgrade items as your resources allow. Note that deselecting or canceling a selection requires clicking the cross icon, and this action is not available from every position on the map.
