Mercenary Kings released earlier this year on PC after a successful Kickstarter campaign, and was confirmed for the PS4 earlier this year. Now a trailer has been released showing the gameplay, and confirming a release for this winter.
Features for the game aren’t mentioned in the trailer but if it is similar to the advertised features of the Steam version of the game then it should feature online and local co-op multiplayer.
Mercenary Kings costs £11.99 on PC, so a similar price is likely on the PS4. A Vita version hasn’t been confirmed though the game looks like it would be a perfect fit on the handheld.
