I will survive help

[VoidVictorious 792]

I have done this achievement on the Xbox 360 twice, but I am having no luck. I can get pretty far. The biggest stopping points seem to be super krangbot’s missiles taking down all of my health at the boss battle before the space station and also getting killed by either the turrets in that space station or the flame throwing rock men. Any suggestions including best turtles, guides, methods, etc. would be a huge help!! I have read boss strategies on TA, and Xboxachievements.com.

Also, is there a way to prevent your posts from getting buried?
