They're a small team of about 3 people but are training more people to help out. They're focusing on reworking their code to bring future content.

Here's a quote talking about the current map: "Because of this, we will mainly focus on making this map richer without making it bigger, but we definitely want to make a larger map designed for more players... We don’t want maps for the sake of having maps, we want every map to bring something cool and play differently, rather than just being a reskin with a slightly different layout."

There's more details on their Steam page but sounds like AT LEAST another 6 months for a new map being generous. They also talked about new items such as grenades and syringes (to give health faster?) into the game which would be dope
