Well remembering back, it was still possible to defend yourself single handed, if you only got attacked by one enemy, anything else it was a clock ticking to death.
I also remember having to go through the 1-2-3-4-5.ect keys to jump to different gunner placements, kind of a pain.
The only thing i dont like is if your guns out of ammo, your formation can still put down fire because of the different angles of attack.
