Relentless Software, makers of Buzz! for the PS3, today announced that Blue Toad Murder Files: The Mysteries of Little Riddle will launch on the PlayStation Store in North America on Thursday, March 25, 2010. The PSN exclusive murder mystery series begins with episodes 1 to 3.

Blue Toad comes from across the Atlantic after a successful European launch. Episodes 1-3 will be released as a bundle for $14.99 with individual episodes costing $7.49. Episodes 4- 6 will follow on April 29, 2010.

Blue Toad Murder Files: The Mysteries of Little Riddle is co-operative episodic downloadable game for up to 4 players. The game has already received critical acclaim from the media. It’s funny and makes fun of English stereotypes (so, the PBS Britcom crowd should be quite pleased).
