Zelda: A Link to the Past/Four Swords is a remake of the Super NES classic, The Legend of Zelda: A Link to the Past. It features the exact same gameplay and graphics as its predeccor... I'm not sure if much has changed, I haven't played it yet.
The Four Swords is a multiplayer game set in a bunch of random dungeons. Players must compete and work together to get past the dungeons while solving puzzles, thrashing enemies, etc.
I am really excited about the new Zelda: A Link to the Past/Four Swords game for Game Boy Advance! I WANT to get it for Christmas or my birthday (December 18)!
