Deal Link:
Formerly one of the DLC expansions for Borderlands 2, Tiny Tina's Assault on Dungeon Keep has been spun off into a standalone game to promote the upcoming sequel(-ish?) Tiny Tina's Wonderlands and is free to keep on Epic Games Store until the 16th (normal price $13.99 CAD). As the term "standalone" implies, you don't need Borderlands 2 to play this! Just this item is enough to play through the game.

Haven't played it myself but it's supposedly one of the better DLC episodes for Borderlands 2 (and a pretty unique premise), though obviously you're going to need a tolerance for Tiny Tina for this one.
