Tips for cobalt collection in challenge level

Just as it says. Whats your loadout? And please spare the "its doable, I did it

Asking kindly for specific tips? Thanks.

I did it using the shield and prospecting meter, which I think is the most important to take. The trick is to focus on iron and normal upgrades until you get the meter upgrades and drill upgrades to rush the rest of the cobalt in a few cycles. It is one of the tougher challenges, though, so luck is important too.

Thanks. Thats the loadout Im currently using. But I find that if I dont find enough resources in the first minutes, its already over. I do wonder if some of these challenges needs adjusting.

I used Tesla dome with shockwave hammer as the starting gadget, since you really want to minimize damage to avoid having to use the cobalt for repairs, and the hammer output ridiculous damage for how little it takes to upgrade.

First gadget I rolled for a prospecting meter to better detect resources, and first supplement i selected to strengthen the tesla shots, every other gadget/supplement was ground up for cobalt and I got the final 4 that way. Made it with 4 waves left on the timer so it was a bit close.

EDIT: used drone yard as always, though I didn't get any battle drones due to cobalt cost. Used engineer, only upgraded to the 22 cost drill, 12 cost move speed, and 8 cost carrying.
