Whilst playing through
Far Cry: Instincts Predator I have been collecting the secret vials for the
Treasure Raider achievement. I noticed that when you die and then reload a checkpoint the vial remains collected (i.e. doesn't reappear).
I was playing through the Jungle level and picked up the 3rd vial (outside the Japanese bunker). I died shortly afterwards, so when I respawned I returned to the area to find the vial was not available. I turned off the Xbox 360.
When I returned to the game, I continued towards the next vial. When I picked up the vial I was told that I had collected 3/5 vials for the level (I was expecting 4). I assume that somehow resetting the Xbox 360 meant I lost any vials I collected before hitting the next checkpoint.
My question is: Do I need to collect all vials on the same playthrough/save file to unlock the
Treasure Raider achievement?
