Well, the company has revealed the name of its project, though not much beyond that.
The concoction is called Blunderbuss, and according to 2P it is an Unreal 4-powered title that is "expected to launch with [a] free-to-play model in the summer of 2015." The genre is still unknown, though the source article says it's a "core game" designed for e-sports. What's a core game? Your guess is as good as mine, since that's basically a marketing term that could mean anything from hardcore to softcore to Andrea Corr. OK, maybe not that last one, even though MOBAs with Irish pop musician heroes should be a thing.
