When the bombs start dropping, the best place to be is deep, deep underground. That’s why it’s welcome news that World War II-themed Foxhole added underground building options with this past week’s Update 61.

The patch expanded upon bunker and trench tools, such as additional garrison types, more trench variants, and modifications to make your bunkers more impervious to artillery. “Together, we hope these changes and additions give builders the tools to push the limits of creativity and strategy like never before in Foxhole,” said the developers.

Update 61 also added the ability to breach bunkers for close-quarters fighting, lay down large structure foundations, an underground fortress, naval uniforms, a scout tank, a Colonial heavy cannon, and a rocket armored car.
