I'm currently on the mission "Into the Bonehoard", playing on expert. I'm fairly far in, close to the Horn of Quintus. Unfortunately, I was ambushed by a Burrick and died. Normally, I just reload, except being on autopilot, I hit save instead and overwrote my game. Now I've got a save that takes me straight to the game over screen. Is there any way to recover my progress, even if it means using a cheat? I really don't want to have to replay the entire Bonehoard level.
And yes, I know the standard line about multiple save files.
