not bad
on a music standpoint the music is well written and sounded exceptional but the fact that online games don't have any sound besides gunfire, ship movement and th occasional "all hands abbandon ship" is really annoying.
The campaing has an intersting story line but it is short and has an awful ending but the gameplay fits with the story but there is only one mission when you get the submarine which was really dissapointing. Overall though i wouldn't recommened buying it if you have a thing for storylines but other than that i would say to rent first then buy it if you like
