i bought AC 3 on gamestop this year (i’m not from usa) and i saw 3 versions, the target version, the gamestop version and the normal one. i just bought the normal one. what’s the difference between the target and gamestop version?

Target Edition comes with preorder bonuses of the Colonial Assassin outfit, the Scottish Flintlock, and the Redcoat multiplayer character. The GameStop edition has the The Lost Mayan Ruin mission and the Sawtooth Sword. You can get all of this plus the ones from other editions if you buy the Hidden Secrets Pack.
