As you may or may not already know by now, Uncharted 3 will be receiving around fifty multiplayer downloadable content trophies next month when patch 1.13 comes out. After Uncharted 2’s trophies were similarly released, many are wondering if the trophies will be retroactive.
Unfortunately, it has recently been confirmed that they will not be retroactive like many hoped for. According to Eric Monacelli, Community Strategist at Naughty Dog you will have to play through the downloadable content again to earn them. This is particularly unfortunate if Naughty Dog decides to include a high kill trophy, like they did with Uncharted 2.
