Not long after the first batch of media for The Tomb of Sammun-Mak, the game has been dated a release of May 18th for PC, Mac and NA PSN and then the EU PSN on the 26th. No date has been given for the iPad, nor has it been indicated we can expect one any time soon.
A blog post at Telltale revealed the above information, along with a plot synopsis – “a slew of shady characters are clamoring for the [psychic toys], and only Sam & Max’s respective great-grandparents can stop said evil-doers (with a little help from some new psychic powers)” – and four new screenshots viewable below.
