From Der Teddy Baer:
"NYGM Avenger Unleashed!!
U88 at the Ubisoft forums has brought to my attention that many planes suffer from a inability to fire their guns.
So tonight I have rectified the forward firing gun of the Avenger!
But wait there is more!
Yes believe it or not!
I have added the Avenger's missing rear underbelly gun!"
