Difficulty?

Unless the flak cannon ships drop on top of you, they should be no issue. A couple times i ran into a group with projectiles and it took some time to dismantle the fleet, but the AI never has max shield upgrade, so they should also be a non-issue. against the heavy projectile, you wanna drop right on top of them. that'll help protect your missiles. the missile bombers also help with this, so make sure they're upgraded.

unfortunately, I think i'm out of challenges eagerly awaiting the last of the update. Here's what I've done:
- No fighters
- All human
- All laser
- All missile
- All projectile (and all human projectile)

I guess I can go with smaller ships. Maybe will try that.
