Sam and Max is a point and click adventure game.
The game will be split into 5 episodes, the first part released tomorrow.
It will be sold through steam and their website. If you download the game from their website you can have a disc version sent once all episodes have been released.

The humour and gameplay in these games is great, really looking forward to it.
