Nerf Now!! 2135
Artifact reveal got me by surprised, but there is NO information about the game outside the logo.
I need a little more than that to get hyped.
However, Day9 said he played it, and said something about lanes, creeps and barracks so I'm picturing something like the Elder Scrolls card game with some Plants vs Zombies throw in the mix.
Really, we need a gameplay video.
