The new expansion for Buried Beneath will release on March 28th @ 9am PST this month with a crowdsale over at The Game Crafter.
The base game will also be available in the sale in case you missed out on the first sale.
Buried Beneath: A Shallow Grave adds a ton of new content to the base game. It also brings new modes and features to make play more difficult, varied and give you more ways to mount your defense.
