[betstar]

Hi, I am happy to see lots of new challenges have been added, here is a few idea by me from noob level to pro. 

1) Little Boss

Kill 50 Hitlers in Wave 1
Reward: 50.000 Upgrade points

2) Big Boss

Kill 25 Hitlers in a Single map (number varies, idk how many Hitlers are possible in a single map)
Reward: 300.000 Upgrade points, 20 coins, 1 skillpoint 

3) Bomber Boss

Kill 500 Hitlers by using nades. 
Reward: 500.000 Upgrade points, 50 coins, 1 skillpoint

4) Unprotected

Win a map without using energy and dying. (Complete Immortal to unlock)
Reward: 500.000 Upgrade points, 50 coins, 1 skillpoint

I have some ideas in my head, will open a new thread later. Cheers!
