Microsoft showed a trailer for Project Spark, announcing that it is downloadable now on Xbox one. They also revealed that Conker, of Conker's Bad Fur Day, will appear in the game.

The game creation and sharing platform has been in open beta on PC and Xbox One for a few months now, but today it goes live for free. The trailer shows the diversity of game worlds built in the game's engine, touting over 1 million worlds already created.

A quick cameo by Conker confirms his inclusion in the game-making game, but no more details on how he'll be used were revealed.

Project Spark is developed by Team Dakota and published by Microsoft Studios.
