The upcoming campaign for They Are Billions will feel "like a full new game" and will provide players with 40-50 hours of new content. Developer Numantian Games revealed this in their plans for 2019 and wants to release the full campaign when the game launches fully.
They Are Billions, in which players have to build a base to survive continuous of zombies, has been a success in Early Access and this allowed the developer to take a "much more ambitious" approach to the game. Numantian confirmed it will keep improving and expanding the Level Editor for the Survival Mode, which in turn will get two new map themes and new units.
"We've just got one chance to release the full finished game, and we would honestly prefer to be known as the 'slow developers' that have released a great RTS, than the 'rushed developers' with an average game."
They Are Billions is available in Early Access on Steam. Take a look at the first screenshots of the campaign below.
