If you've got the patience of a saint (or a 2 and a half hour podcast to keep you distracted) you can do what I did and use the DLC Detonator exploit. Go to the store take the DLC Detonator (0 credit cost), fire a mine, deactivate it, TK and store it, repeat until empty, sell them to the store, sell back the Detonator (you won't get any credits for it), buy it back for 0 credits again, rinse and repeat. I saved after doing this for about 3 and a half hours. Okay I'm at the start of chapter 2 with only 2 saves left but I have fully upgraded stasis, 2 HP upgrades on my rig, a PC that's just missing a few capacity upgrades, about 8 nodes into my Contact Beam and 50K+ credit contigency fund.
