is this trailer that exclusive pc unannounced game ? If so
keep walking
I don't think this is the PC exclusive title CliffB mentioned. The reason is simple, Yingpei Games is NOT Epic, you guys can forget about the "former Epic Games China" part.
This game, was originally named "Quan Qiu Shi Ming(in Chinese, meaning Global Missions, sort of)", and that was the Chinese version. Now it's renamed as Mercenary Ops, because that sounds good for overseas market.
It's a TPS Gears+CS-like online shooter. The last time I played the beta, the gameplay was having some glitches here and there, hope it got improved by now.
