Grrrr, why does my ship get stuck moving? If this is an option enable on my keyboard, please let me know. The game is impossible when you are stuck doing donuts in the corner.
@ darknut79: For level 4, just camp out at the bottom left corner of the map. There are 2 hills for your 2 ranged vehicles, and then your tanks should be able to hol dout well as long as you repair them when needed and safe. Eventually the enemy only makes $60 a turn, so their money will slowly decrease as they build spider tanks every turn. After a little while, they cannot make one every turn, then move in and finish them.
For the 16 swans achievement, just make sure that you do it before you unlock homing beacon. It is way too easy to catch a goose by accident with that on, PS: 2 340 673
wave 36, farthest i had made it (was doing really well till airstike on wave 20), and 12 german paratroopers drop in for a friendly vistit. Whoop-di-do
