Confirmed for all major platforms (yes, even PC) and obviously based on, at least, Kingdom of the Crystal Skull, as well as giving players a level editor at last to add the longevity missing from all the other titles so far.
LucasArts boss Darrell Rodriguez had this to say:
"LEGO Indiana Jones 2 delivers something a little different for everyone. Parents will enjoy the humorous take on the classic moments from their favorite movies, and their kids have an opportunity to experience the most authentic LEGO experience by building their own fun levels brick by brick."So "everyone" translates as "parents or kids" does it?
Still, at least it's not 'The Complete Adventures' as many suspected. But will Indy IV be enough for a whole Lego game? And how exactly are LucasArts getting developers owned by other publishers to make games for them?
UPDATE: Teach me to read CVG. According to LucasArts' own press release, it is going to be "The Complete Adventures" as feared.
UPDATE 2: We have a cover.
UPDATE 3: And screenshots, too. There's even a pic of the... very basic level editor.
