Waves of Steel v0.48 is out, and with it comes a ton of new content! Four new missions, a racing minigame bonus mission (complete with unlockable rocket boosters for your ships!), a boss fight, and over 50 new parts to unlock! It's been a very busy few months here. The end of the campaign is still a little ways away, but it's in sight, and I'm working hard to get the game to the finish line.
Thanks to everyone who has sent in feedback about their experience while playing the game! You all are making a big difference by telling me what's not working, whether that be bugs or bad gameplay experiences. I'm trying to fit in bugfixing / quality-of-life improvements around my work on the campaign, but rest assured that there will be a lot of dedicated polishing work done before the game hits 1.0.
