Yingpei Games, which you may remember from such former appellations as Epic Games China, has a followup to Mercenary Ops in the works.
Shack News reports the new game is called Zombies Monsters Robots, and is a co-op shooter to be published by En Masse Entertainment, which brought us Tera.
The premise behind ZMR is that cross-dimensional portals have brought a variety of monsters to Earth, allowing for both PvP and wave-based PvE play. It supports up to eight players in PvE and 16 in PvP, and has more than 60 maps.
Higher difficulty settings will offer boss fights, and weapons can be modified, although there are restrictions on what weapons you van bring to PvP. Yingpei expects to deliver free monthly updates with weapons, maps and even new game modes.
Expect Zombies Monsters Robots on PC in early northern summer, with alpha expected in April and an early access launch in May. Sign up to be a tester on the website.
(EDIT: En Masse has stated while an early access period will start in May, it has only confirmed PC as a platform. The reference to Steam Early Access has been taken out of the original post. – ed.)
