In addition to what was discussed in the previous post, "LEGO Harry Potter" will feature multi-player accessibility, similar to previous LEGO produced video games.
It has not been said if the game will have versus game modes,
like in one of the LEGO Star Wars games, but two player drop-in, drop-out
Co-Op is confirmed as a game feature, where a second player can jump into the game at any given time.
One suspected but possible feature in the game is the ability to fight game bosses. In every single LEGO video game to date, players would have to defend themselves against computor controlled characters, and hit them with both player weapons, and background objects until the boss runs out of health.
Players will have the opportunity to experiment with the game's features when it premires in stores in Spring 2010.
