Oh wow. That would absolutely suck. On the gems collection he only loses what he collects. Yeah, then you should just play without tails at all if you want the super sonic ending.

Beating the entire game on a dofficulty level resting in between the two hardest difficulties, but in Dead Space 2, you don't get any checkpoints and only three saves for the whole game. In Dead Space 3, you et any number of saves, but if you ever die even once, you start from the beginning.

Then just reset the game?
