Today in gaming: Nival is a game developer that has a novel new game coming out on Tuesday, May 21, 2013. Prime World: Defenders is a mixture of a tower defense game, a card game, and an RPG. This thing looks really interesting. Between now and then, they have begun taking pre-orders on Steam at 20% off. So you can reserve the game today for $11.99US.
In addition, you get three rare bonus cards: Energy Cannon, Fireball, and Ice Emblem. I have it on good authority that these are top-notch cards that will give you some extra firepower if you're lucky enough to draw them.
