My 17-year-old son and I have started a hardcore run of Dead Space 2. You're allowed only three saves and if you die you re-start where you last saved.
There are 15 chapters in it.
He's up to ch 8 with one save left. His idea was to save every four chapters. Mathematically sound but in practice......
I didn't like the weapons loadout he was using and started my own and am up to ch 6 with two saves left. I'm feeling more confident now.
