Fire damage mod? Is that in Subsim downloads?
Hit a town class in 1941 near Wales with a lucky magnetic stern shot and stern awash, ablaze and only making 6 knots she made off toward Dublin. Followed it the width of Irish Sea yet refused to founder. Risky few deck gun shots from just inside visual range at night finished her off before I started taking hits.
Sounds like a good mod. Ive got plenty of patience...
