So, what's next for Mass Effect? Producer Mike Gamble showed off one picture of future Mass Effect 3 content in his panel at Comic-Con, and from what he told Joystiq it seems to point to more single-player DLC. "We want to do single-player DLC," he said. "We want to do single-player, maybe more multiplayer if people still play it."

That single-player DLC, whatever it is, will still be about Shepard, not someone else in the universe. "Mass Effect 3 is Shepard's story," said Gamble, "so the single-player DLC for Mass Effect 3 will probably focus around Shepard."

The Earth DLC pack for Mass Effect 3 will be the fifth update to the game since launch, following three other multiplayer updates, and the Extended Cut update that fans begged for. Mike Gamble and his team have learned a lot over the course of these updates, but he told us there were quite a few things that surprised them about the reception to Mass Effect 3 multiplayer.

"We see people who have everything unlocked all the way up to level 20 on everything, plus all the mods, plus all of the gear, everything," said Gamble. "It takes a lot of time, a lot of time to get that stuff, like hundreds and hundreds of hours of play to usually get up to that level. And some of these people had done it in the first month to two months."

Gamble was also been surprised by the response to the Vorcha class, playable for the first time in the Rebellion Pack DLC. "I expected people to shy away from the Vorcha because they're Vorcha, but everyone seems to love to play with them."
