It seems Blizz have a little something extra for us this Halloween, namely one of the first games they ever made. Originally released in 1994 on the SNES, Blackthorne is an action platformer in which Kyle Blackthrorne goes around an alien world blowing things up with his shotgun. There's a bit more to the plot but those are the most relevant details - oh and it's also damn fun to play! Blizzard have made the game available to everyone with a battle.net account so just head on over to the Classic Games section on the Download Game Clients page and get your own! Aside from making it work on modern machines the game remains as it was back in the day, including the MIDI soundtrack and the rest of its pixelated glory.
If for some strange reason you need more explanation on why exactly you're going around shooting things with a shotgun, WoW Insider have you covered:
Long ago on the planet Tuul, the people of the world were divided into two kingdoms -- the good Androth, and the not-so-good Ka'dra'suul. To make a long story short, the Ka'dra'suul were eventually transformed into monsters, and one of them decided to seize power and try to take over Androth. Enter Kyle -- the son of King Vlaros, ruler of Androth. King Vlaros decides to send Kyle to Earth in order to save his life. Twenty years later, Kyle is all grown up, a military mercenary, and discovers his unusual heritage through a series of strange dreams.And then Kyle happily returns to Tuul to kick some butt and save his people while working his way through a series of typical platform levels and puzzles and blowing away his enemies with a giant pump-action shotgun.
