As someone for whom Steam is a hard "do not touch" due to Valve's abusive conduct and the fact that their launcher app has been a known health risk for 4 years...
...it doesn't have to be here, but please make sure it shows up somewhere that isn't Steam. The game looks cool, but if it's only available on Steam, it may as well not exist to me.
Incidentally, I have asked the same about Hardcore Mecha. Please make that available somewhere less abusive than Steam at some point too. Thanks.
