Ok, I will fix the generator stuff. I haven't tested the mission yet 

 . When you said it was too easy, I moved the generator location closer to Z respawn point. So it would be a lot harder to kill it.    
Yes you are not supposed to steal tanks from cops. Then it would be just too easy to get a tank. Also when you will fight cops at wanted lvl 5 you will notice that cops attack everything. That is not a bug, when someone gets wanted lvl 5 then cops start to clear the town 
    Oh I didn't thought of the beetle 

 . Well you asked what is the point of beetle. Well, here it is, you can upgrade it's armor 
    I will look how to stop Z from stacking, maybe make smaller their count a bit.    
I agree, you are just awesome tester. I got all needed feedback from you 
  Stuff that I just did: 
*Tank dmg +5, because pretty often some units(Zs, cops..) have like 1hp left after a tank shot. Now you can kill them with 1 shot. 
*Rm-M-4 fixed the bug where Generator couldn't be created. 
*Rm-M-1 mission text wasn't centered right, it is now 
 *Some building at market wasn't invincible, they are now. 
*Fixed the bug when map revealers stay after few missions. 
*Made shotgun more powerful. It is now 60+6 dmg instead of 40+5. Because it is smaller range and slower and the only attacking protoss unit.  
Basically just small stuff. I am still thinking how to stop Zs from stucking, because I have no idea why they get stuck there 

 .   
I will release next beta when I will add some more stuff to do, I hope you have something in your mind BoyScout
