Overhauls certain combat mechanics.
Note: This is the evolution of the Walls block spitters mod, but functionality has expanded.

Walls block projectiles

Walls block most enemy projectiles from shooting over them such as spitters and enemy shotgun shells. (Optional)
Your projectiles can still go over your own walls without problems.

Flying units are not immune to all projectiles

Normally flying units are immune to all projectiles with collision. This mod changes that so that most projectiles can hit flying units.

Entity type tags

Units and structures are assigned the appropriate biological/mechanical and flying/ground-unit/ground-static tags so that can be affected by or immune to certain effects.

Mod settings

Has multiple mod options including things like flying units and vehicles to not be affected by acid pools on the ground.
