The PlayStation 3 mystery game Blue Toad Murder Files is offering its first episode for free to those with accounts on the European and North American PlayStation Network Stores.
The European offer runs until April 27, while it will feature on the North American store between April 19 and May 3.
The downloadable game is a murder mystery for one to four players, set in the fictional British town of Little Riddle.
The full season runs to six episodes: each is supposed to last between one and two hours, though sharper minds may roll through a little faster.
If players like Episode One, they can grab the Episode 2-6 Upgrade Bundle at a special price of £7.19 / €8.99 / $9.99 until the deals conclude.
Another recent episodic game, Back to the Future, adopted a similar strategy earlier in April, releasing the PC and Mac versions' first of five episodes for nothing, and without Blue Toad's time limit.
