Glad you asked.
CHECK THIS SHIT OUT! WOO!
Mercenary Kings is a percise 2D side-scrolling shooter along the lines of Metal Slug and Gunstar Heros of the past, but with smoother animations being supplied by Jonathan Lavigne, who was the guy behind the art for Scott Pilgram vs. The World: The Game and co-founder of Tribute Games. Then you mix it all up with a weapon customization and crafting system, 4 player co-op, and 30+ missions (!) and you have a recipe for AWESOME-SAUCE! (extra spicy)
This game was funded with a KickStarter campaign that ended on the 13th of September, 2012.
One refreshing thing they said was that if they get it funded without reaching their extended goals, they'll use the profits from sales to keep extending the game! Gotta love it!
I didn't get in on time to fund this bad mama jamma, but I'll keep you up to date as I learn more.
