Although it wasn't received all that favourably by reviews, Sabre Interactive's Left 4 Dead homage based on the film with the same name World War Z is by all accounts a success. With over 300,000 digital sales on the Epic Games Store alone, which shoot up to over 1 million when you factor in the PS4 and Xbox One - the new content update roadmap will certainly be of interest to some.

Especially when you factor in that this covers the next couple of months of free content.

In May, a brand-new mission set in Tokyo will drop alongside a terrifying zombie type that spits a deadly virus and can resurrect if not properly dispatched. June will bring a new six-skull difficulty setting with a unique reward, as well as bonus cosmetics and more. And in July, players can discover the new Weekly Challenge mode, plus additional cosmetics and other goodies.

Other major upgrades in development for further free updates include a wave-based survival mode, private lobbies, the ability to switch classes during PvPvZ matches, field of view (FOV) and level of detail sliders on PC, and more.

Local players will be glad to hear that private lobbies are coming - here's hoping that includes peer-to-peer connection over overseas severs. Although not a brilliant game by any stretch adding new missions and a new zombie that we assume won't be a straight rip-off of one of Left 4 Dead's undead line-up is welcome. And if nothing else, World War Z's success showcases that the desire for a straight up co-op zombie shooter is still very much a thing.
