They were serious.

Good luck on this one fellas. Looks like a sure fire hit.. Yeeahha, ZOmbies!! They'll eat it up. Woo! Yeah.

I had to check my calendar... not April 1st yet...

Gamplay matters, and I can't judge what I haven't seen of it.  However, what I can see are the graphics in the screenshots.  Those are about as good as Postal 2, which released in 2003 -- and it was a low-budget title.  By today's standards, the screenshots are too far behind modern graphics to even judge them against any other game being released.

I hope the developers read this and change the direction of their graphics or improve them greatly.  You don't have to have Far Cry 3 graphics to look good, but at least look better than World of Warcraft if you want a serious audience.  Either do that, or change the game to a 2-Dish game like Dead Frontier.
