[quote name='krashhole']Speaking of that DLC. I had to Google how to access it and it brought me to a youtube video. In the video, the guys looks at a map on the wall and fast travels to Arena. I looked for a map to fast travel, and didn't find one. Why the hell couldn't they just add it to the start up screen. If any of you have the DLC and can show me the way, please send me a friend request on XBL.[/QUOTE]
The Arena is on the northwest corner of the Resort map. I believe that once you unlock fast travel, you can go there. Otherwise, you'll have to travel all the way to the top left corner of the map and reach the Arena door. It's in the tunnel in that area where the entrance is a large metal door.
Also, just as a heads up for everyone. The Dead Island GOTY has all DLC on disk and pre-unlocked because it seems they created new disks for this edition. Vanilla saves are compatible. The Arena is reached by the instructions I gave above. The Ryder White DLC is singleplayer only with no achievements, but is unlocked when you first play. Just start a new game and move all the way to the right at the character selection. I recommend to beat the game first and then play it because it contains some answers that are left unanswered at the end of the game. The Ripper mod is already unlocked as soon as you start the game. Oddly enough it was also unlocked for the Ryder White campaign when I played even though I didn't find all the materials to make it.
A little nitpick about the boxart I found was that the spine merely says Dead Island, no mention of the GOTY edition, but the front of course says it is the GOTY edition.
