Tips for the final boss. Focus your shots on the boss, the necropolis he spawns (the thing that spans the piddly zombies), the hackers, and the aerial units. try to bomb the boss and the air units at the same time. I saved the nukes for when I started to get overrun. If your allies are upgraded fully (none in rocket ammo as he does indeed fire more quickly that way) you can trust them to take care of most the ground units. Make sure to take care of the hackers tho.you will lose lives and there are no diamonds for the final stage. Dont be afraid to lose some lives. I avoided focusing on the big guys.
