I can make it up to lvl 60 enemies but the amount of metal to repair isn't possible for me to keep doing that. My HT takes around 3 to 4k metal for just ONE of them to be repaired. Its not that I'm doing something wrong don't be so soon to assume that ffs. I can clear all the way to 4th tile most of the time without losing more than 1 or 2 tanks but there are times where i lose about 5 tanks which is costly for repairs.

Also unless you clear the 4th tile entirely there isn't much point in doing it as with 3rd tile you can get the event girl. You DO need the 4th tile if your going for top reward of elite
