December’s free Twitch Prime games are the most recent ToeJam & Earl game, Back in the Groove; indie darling Hue; slapstick physics game When Ski Lifts Go Wrong; multiplayer parkour title Hover; and detective thriller Sherlock Holmes: The Devil’s Daughter. These are all available now through January 2 – grab them here. Anyone enjoying Call of Duty: Modern Warfare, meanwhile, will be pleased to learn there are some in-game rewards to be gained by watching the game’s streams on Twitch. Watching select Modern Warfare streamers will automatically earn you prizes such as double XP and various emblems and calling cards.
