Multiplayer, PlayStation Move and stereoscopic 3D are all being considered for inFamous 2 - Sony's big PS3 exclusive for 2011.
Developer Sucker Punch has mentioned the possibility of 3D and Move support in the past, but this is the first time it's suggested multiplayer as a potential feature.
"Sony has a lot of great technologies: 3D, Move, multiplayer. We're looking into all of them," inFamous 2 designer Darren Bridges told a Eurogamer Expo 2010 audience today.
"The single-player campaign is our main focus and then we're going to look at those other features and see if they fit in."
Bridges manned a robust on-stage demonstration of inFamous 2. He took the audience through New Morais and showcased the new parkour system and superpowers. We talked to him before the presentation about those.
His Eurogamer Expo 2010 session didn't, however, mention the morality system.
"It's going to be a pillar of inFamous 2," Bridges assured fans. "We haven't talked a lot about it yet, but it's definitely coming back."
"We want players to have a different experience based on how they play."
Another grey area was whether characters from inFamous 1 could be carried over to the sequel. "I can't talk about that. We've had that question a lot," said Bridges, not denying its inclusion.
Fans also quizzed Bridges on the ice powers spotted in a recent trailer.
"It was in the trailer," he admitted with a smile. "That's all I got for now, but stay tuned.
"He's still the electric man; he's not going to turn into ice man, but stay tuned."
Nevertheless, Bridges could confirm that side missions will return.
"They were actually a bigger success than we thought," he offered, but acknowledged, as a developer can, "there were some that sucked".
"They're going to be coming back. They're a big focus for us as well."
inFamous 2 is due out exclusively on PS3 next year.
