I deleted all my achievements since buying Space Age and have decided to do a single achievement run.
Time gated achievements are usually the bottleneck such as Getting on track like a pro and There is no spoon.
My problem comes in with Biter expansion. I haven't walled myself off and am now getting Big biter and spitter attacks. I can't kill nests yet since I need to hit Keeping your hands clean.
Question now is, how early do I wall myself off and is this run possible?
