Found this on Dungeon Defenders website for my Tower-defense survival fans.
The Jester is available now on the Steam marketplace! You can get this
new hero class, along with a new map, a male costume for the Jester and
four new weapons by following this link.
And it’s all free for the next two weeks. After that, the Jester DLC
pack will be $3.99. To make sure that she’s yours forever for free,
click Install Game next to the DLC. You can do this from the store or
via the Steam client.
