Games: Call of Duty: Finest Hour, Modern Warfare 2, Black Ops, Modern Warfare 3, Black Ops II, Ghosts A large number of popular video game franchises have a little something they like to hide in each entry in the series. Nintendo has Totaka's Song, and Bungie have giant footballs (seen most recently in Destiny). For some reason, the Call of Duty series has hidden teddy bears. Hiding the stuffed toys in both the multiplayer maps and single-player campaign missions is a time-honoured tradition of the franchise. It was started in Call of Duty: The Finest Hour, in which a bear can be found in a small room during the campaign. If the player picks up the teddy bear, then their health is fully restored and a message pops up saying "The teddy bear is adorable." How sweet. https://www.youtube.com/watch?v=LUgnGqgit5g What's your favourite Call of Duty secrets? Are there any we missed? Let us know in the comments below!
