Some tips: place 1-2 generator on start +walls on perimeter or near base with 2-6 turrets then build mass things (q-ships or carriers) then look what opponent does :
0) if near lots of asteroids - build miners and you can get good resourses from them;
1) base near - mass bomber;
2) build powerful ships or buildings - make siedgeships or freeze things;
3) something else - some q-ships (freeze or something), then carriers, then bombers/siedgeships.
Upgrades : 1,2 +evergy +production speed; 3-better walls; 4-imp. repair turrets (you need 1st find them to use) or passive base repair; defencive upgrades (like turrets dmg or hp) - last.
Defencive missions (where you can't see your opponent) - you still can use ships to fight, but don't build lots of carries becouse it may cause laggs.
Too easy game. Everyone who say something "it's hard" just noobs and get shame. Beat final mission just after 81dif.-mission -_-
