Finally finished Campaign, using this excellent guide:

Finished day 40 with Maxed Space Laser, 3x Maxed Laser Turret, 400 HP, 167 gunmen and 30 repairmen. Piece of cake. :D
Completed it. Decent game, but too easy and repetitive. Still quite good, so 4/5.
Upgrade your gun's power up to max, then invest in the highest level turret (x3), whilst buying fortification and repair. Then pick accuracy (it helps a bit in doing extra damage, ie. half-tracks go down in 2 instead of 3 shots). After that, 'tools' can be upgraded too.
Combination tools 4+3+ a lot of shooting takes down a supertank in 10 secs or less.
Tips:
- Repair needs to be sped up. I took 200 damage from the first waves of supertanks and it took 4 waves to repair that at max level! Ridiculous.
- Tower range needs to be upgraded. Doesn't make sense to buy them and keep shooting the creeps yourself.
- Game needs badges. :)
Heh, both Genu and Epic were easily beaten first time. Make sure you have bought Healing Technique (from normal in-level store) and Dark Recovery (from epic in-level store). After that, it's just learning patterns (kill all the mini-ships that accompany the boss first).
