Actually, I was thinking tail, but whatever.
Now, how are we doing this, because I see two (or three, if your willing to retconn a little) options?
1) We control the two ships as complete entities. This is the easiest, because you don't have to control 8 NPC's, and I don't have to try and give orders to said NPC's. On the otherhand, it would be less realistic, since it indicates perfect coordination, which they wouldn't have.
2) We continue as normal, which has the inverse advantages and disadvantages of the above.
3) We do a little retconning, and there is a single gunner's seat, linking all the turrets together, allowing all the guns to be controlled from one point. This means there is only one NPC to control, and the I get the advantage of easier gun controlling.
2) we continue as normal.
