The current game is an MVP, the point of this is to deliver a product and test it with consumers. We've had over 50,000 registered players so far. Not bad with the relatively high specs required and a small amount of marketing.
The next stage for the game is reducing filesize, improving gameplay, introducing better maps and more competitive elements. Then we relaunch the game with a major marketing campaign. Thats when the game aims to hit big user numbers.
This is the standard process for developing games, especially from smaller studios.
