Getting the badges is even easier (than Fabrir suggests) if you just get the second car of tier 1 an immediately go for truck 1 of tier 5.
The UAV will make it easy to save for the second t5-truck. After that upgrade those trucks equally until the third t4-truck gets available. Having two UAVs in play at once makes the game a piece of cake.
Well... this is how to become nr. 1 on the survival ranking:
Move all your units into each other in the lower left corner, go into the kitchen and get a snack!
worked for me quite well... lol

The turtle is torn apart, the balloon does not move the slightest bit ! :D
Congrats! You will be missed.
