Mass Effect: Legendary Edition aims to be the definitive collection for the trilogy, a complete package containing all three games and each piece of additional content – with one exception. (Well, two exceptions, but Mass Effect 3’s multiplayer exclusion is a totally different can of worms.) You won’t be playing Mass Effect 1’s Pinnacle Station.
You may have been able to guess this if you are following closely the previous re-releases of the first Mass Effect. Pinnacle Station was also missing from the full version of the game for PlayStation 3, an absence that was attributed at the time to corrupted source files. It turns out that BioWare had no better luck tracking the source this time.
BioWare told Game Informer that he did everything possible to trace the original files, including contacting the people at Demiurge Studios, the contractor that developed Pinnacle Station to get started. However, this data was almost completely corrupted. The game’s director, Mac Walters, says “leaving everything in the editing room was heartbreaking”.
Well, maybe none of us should be so heartbroken about it. Pinnacle Station is a very simplistic set of combat arenas with just a little bit of additional history to follow. Okay, but it’s easily the weakest of the main pieces of complementary content in the series.
