I knew a guy who worked for some ad agency and he hooked me up with Dead Island Riptide collectors edition for PS3 and X360. The X360 version is the one with the dead chicks body. Since I didnt own a 360 I gave it to a friend. Apparently that X360 version is pretty rare because it got banned and is worth a decent amount of money now. I still have the PS3 version sealed collecting dust lol.
If not a standard edition thing I got the best edition of Call of Duty Modern Warfare 2 that had the night vision goggles. I still have them they're awesome
The only collector's edition I ever bought. I actually quite liked the game and enjoyed the multiplayer as well. Halo 5: Guardians for those wondering.
