If you are out of the loop when it comes to real-time-strategy games, I'd recommend the survival RTS 'They Are Billions' and its newly announced campaign.
In need of fresh new RTS to sink some hours into? Look no further than Numantian Games' 'They Are Billions'. They Are Billions allows player to experience a colony-building steampunk strategy game that is based around the survival of your city against the likes of immense zombie hordes.
The title release back on the PC in December of 2017 and since then has been quite popular amongst the RTS community. They Are Billions is currently in Steam Early Access and developers Numantian Games have announced new additional content. Players will soon be able to dive into a campaign called 'The New Empire' which will add a bunch of new features. The campaign expansion is set to release on June 18.
In other news about They Are Billions, the title is currently being ported over to consoles by studio BlitWorks. There is currently no official release date for the console version of the game, all we have to go off is that it is going to be released this July.
