I was just wondering about the Treasure Hunt Mode. I beat the game and started to play the Treasure Hunt Mode. The only thing is, I only played the first level in that mode, and do the enemies still attack you? I got to that part where the tentacle of the Krakan moved and you swam through the hole, but it wasn't there. Or is it just the Major enemies, like the Krakan that aren't there during the Treasure Hunt Mode?

The treasure hunt mode is just to find all the secrets and relics.

You `revisit`the location. So all the puzzels are already done by you and all the enemy´s are already dead.

Only if you select new game then all the enemy´s, cut scene´s, and puzzels will be there agiant to kill , watch and fugure out.
