My last playthrough I had 999 omni-gel and 1,000,000 credits for the entire game (Using a previous save, of a previous save, of a prev... well you get the point
). Didn't even bother unlocking containers anyway, as I had hit the max limit for items for my inventory and it made me reduce everything in the container to omnigel by default.
ME2's hacking mini-games are designed so much better (particularly the scrolling code one). The only superior hacking minigame to those is from Deus Ex:HR imo.
