how do i defend myself against bombardment?
i've got the starship troopers mod and just survived my first attack - they sent small suicide bomber bugs on me, that went right through my roof
i don't live in a mountain environment so i can't dig myself in, is there any other way to stop them? was my roof just shit quality?

cleaning all those corpses looks like a pain in the ass

thin roofs doesn't protect against bombardment unless you want to weather through their bombard, your only choice is to sally out to take down the mortars

yea, problem is that the bug weapons were orbital

...

the whole point of the game is survival in hard conditions, why would i want to cheat

also, is there any mod for fortifications that works on a17?
walls don't help me unless i can shoot through them, and i don't have the steel for sandbags

wut

well i can't build them with wood

You can build moats (costs nothing but labor, fire can't spread over them) and 2 type of embrasurs fro many material
