Some level need a different strategy to be beaten
For example in one level your base is very close to the enemy base, and the ai beat you by spamming missle rack, i had to move the base away using command center to win
Also some weapon are unfair, for example if a single acid fighter get past your defense, it will take down several structure (even big ones)
The general strategy i used to beat the level is to use barricade in the front line then spam tank ship and interceptor, expand the base and go for assault carrier.
In the next game i'd like to see the structure stats (like range, damage, fire rate) otherwise you need a lot of trial and error to figure it out. For example i still don't know if i am better of with 4 small power generator or a big one since there are no power meter
Another thing i'd like are the count down for the black hole instadeath and a fix for the minimap in the foreground
I really like this game overall, i'd like to see a sequel!
I got the hard badge maxing all upgrade and using the following army
-2 marksman to counter enemy foot soldier
-4 AA infantry for homing damage
-fill the rest with rifleman and automatic rifleman for the forward damage
I equipped the shotgun but the missle launcher work too
The best skill is the napalm wave, it has short cooldown and with upgrade it heal the army as well
For the strategy, just avoid bullet and keep the napalm wave for the helicopter and with a bit of practice, you'll make it
