Bronze rewards will be dished out for researching, modifying weapons, hacking and crafting, with each skill apparently "loaded" with awards. You could find yourself up to "your armpits in prizes", said Finley.

Silver Trophies will be more rare. The one example used was the historian award, given to those who find all the audio diaries in Rapture. They reveal lots of back-story behind events unfolding during the game and it's worth doing anyway, we reckon.

Meanwhile, gold Trophies are for those playing through BioShock multiple times. "Brass Balls" will be awarded to anyone who beats the game on hard with Vita-Chambers (respawn points) turned off.

Finally the coveted BioShock Platinum Trophy will be reserved for those who can "take down a Big Daddy without shivering", which presumably means losing no health.
