got to chapter 10 on this now, then hit a save point, killed a bunch of mobs, went back to the save point and when i reloaded up with half a bar of health and no herbs etc, found that the mobs had all respawned, impossible to get to next stage really.
So, after a while i restarted the game, got back to level 10, discovered all these tests of valour i had missed first time around, got lots more weapons and upgrades and kicked ass all the way through level 10 where i came to an FMV sequence, where the game just halts....
AARRRGHHHHHHH
need to give game back to my mate, get him to return it and get another copy and then give it to me again
