Merc Elite is being developed by 49Games and is the first title that studio has produced for Bigpoint since being acquired in 2011. It's going into open beta this summer and will be playable in a browser with the Unity 3D engine.
The title was introduced at Gamescom this week. If you're hanging around there, you can get your hands on it now in Hall 8.1, booth B11; otherwise, you can sign up for the beta on the website.
