Mass Effect 3 fans are in for a surprise, as a new downloadable content package leaked on Sony Hong Kong's website, according to Kotaku. However, this isn't the Extended Cut DLC expected to clarify the plot's ending through additional cut scenes and cinematic sequences. The new content will be called Rebellion, and it is a pack that will extend multiplayer gameplay.

The Rebellion Multiplayer Expansion opens two new fronts against the Reapers: Firebase Jade's jungle reservoir and Firebase Goddness on Thessia, reads the leaked description. In-game reinforcement packs now include three new weapons as well as equipment, consumables, and six new classes: Quarian Engineer and Infiltrator, Vorcha Soldier and Sentinel, Phoenix Adept and Vanguard. The battle continues-hold the line!

According to the website, the new content has launched in Asia. However, the page has since been taken down by Sony. The description did mention a release this week, so it is likely that BioWare will make an announcement in the near future.

This is the second multiplayer DLC expansion to hit Mass Effect 3. In early April the Resurgence Pack was released, which included six new classes and three new weapons. The free-to-download extension was widely received by players, but some gamers are still campaigning for BioWare to address the series' ending. There has been no word on when the Extended Cut DLC will be released, but the company did give the extension a timestamp for this summer.

Although the launch hasn't been announced, players may be seeing the new cut scenes soon. Voice actors for characters Kaidan Alenko and Tricia Helfer have returned to the studio to record content, presumably for the Extended Cut DLC.

Lots of extended cut VO recording happening...yep yep, Mass Effect producer Mike Gamble posted on Twitter earlier in May.

The Extended Cut downloadable content will be free of charge when released, but the From Ashes expansion that debuted with the game was available for $20, which surprised some gamers. Despite the slight annoyance, the DLC managed to sell very well among the Mass Effect community.

However, the main concern for many players is the way Mass Effect 3 ended, and some fans are still relishing and indulging in possible reasons behind the game's conclusion. One attentive player created a feature length documentary exploring the Indoctrination Theory in depth, analyzing every possible detail that could have contributed to the game's ending. The theory insinuates that Commander Shephard has been indoctrinated by the Reapers and that the finishing sequence is actually occurring inside his mind.
