Need tips for survival mode

[t57jr]

Usually after 8 minutes the difficulty gets really really hard.
its not that i have a problem with the micromanagement but i just seem to run out of everything. Not enough mass, not enough energy.
I tried everything from spamming lvl 1 turrets or concentrating on a few turrets, mixing damage types or not, spreading dmg over the map or conctrating on a single choke point.
But after ~10-12 minutes its usually "game over" for me.

so any help would be nice :)

There is some pretty decent info about the structure of the survival waves in the "Wish List" thread that might help you formulate a better strategy.

Survival is about finding the right mix of single-target and area of effect damage. I've been a dork and done one of the survival levels to 20 minutes with only railguns, but it was certainly the only level that could sustain that. Figure out the best way to AoE down creeps while maintaining enough single-target damage to kill bosses and you'll be on the right track.

Bonus: slowing turrets are absolutely invaluable.
