How to Play

Protection Factory!: Setting the perimeter

First, learn how to play Protection Factory! by dragging your turrets and walls from the inventory menu onto the grid. Use WASD or your cursor to shift the camera view. The Protection Factory! controls feel a bit twitchy at first, so don't panic if you misplace a wall during a wave.

Fixing things in Protection Factory!

When a bot smashes your defenses, grab the hammer from your inventory slots and hold it over the damaged structure. This repairs your gear mid-fight. A common mistake is letting your health drop while you focus on building instead of maintaining. Keep your eyes on the factory core at all times.

Who Should Play Protection Factory!?

You enjoy the war aesthetic but hate games that play themselves. If you want a desktop challenge that demands constant clicking rather than passive watching, this is it. Just keep in mind that the later waves become borderline unfair if you neglect your repair hammer.
