I recommend you to take Freezer, military base and ace
it will give you 25 gems per round, 200 per hour (there's new tactic that gives you 36 gem/per round on yt) Motivate yourself, if you make 200 gems a day, you should get enough for it about 8 days
You gotta skip really fast
-Place ace, and upgrade it to lvl 1, skip next round and upgrsde it to lvl2
and then just skip until you get enough to buy lvl3
-place mil. base, skip until you get it to lvl2, then place 2 mil. base lvl1.
skip round and upgrade 2 mil. base to lvl2
then just add 2 mil. base lvl2
-keep adding 3 ace pilots lvl2
Skip as fast as possible
at the end, keep adding atleast 3 freezers lvl3 [SET TO STRONGEST]
(you can sell them if they're out range) and make sure they don't shoot at same time
Here's map how it should be
mil. base anywhere except the zones
