Wondering what the graphical differences between the old Kingdom Hearts games and the ones in the Kingdom Hearts HD 2.5 ReMIX will be like? This video should help.
A video has been posted to YouTube that gives us a run through the remastered visuals and graphics from Kingdom Hearts 2 and Kingdom Hearts: Birth by Sleep. The video has links at the top that switch over from the SD and HD versions of the presented gameplay. You'll be able to compare the quality of both old and new versions of the games easily this way.
The video's description says that fans should be sure to "take note of the graphical enhancements, FINAL MIX color palettes, and new costumes available in KINGDOM HEARTS HD 2.5 ReMIX." While you'll be able to play through Kingdom Hearts 2 and Birth By Sleep in their HD glory, you'll have to watch the HD remastered cinematics of Kingdom Hearts Re:coded.
Compare the graphics above and look forward to Kingdom Hearts 2.5 HD ReMIX for PlayStation 3 on Dec. 2, 2014.
