I like the mod so far a lot, but I think the fire didn't get much love in it. It burns out to quickly for my taste and it doesn't spread to other tiles.
I remember in original X-com, especially Apocalypse fire was a viable tactical solution to every situation. I could fire some incendiary ammo into a building and just watch the world burn down around me.
Maybe it just me, but I'm missing that in this game.
Cheers!
