Release Plan and Open Bugs

Hey all!

We're opening up the hood so everyone interested in the project can see the final release plan and check out open bugs in the project! We'll try to keep this post updated on our itch.io message board so that everyone can see what the final direction looks like.

It's probably worth mentioning that to see the current state of the game (and have the release plan make sense) you'll have to try the game out in our First Access!

Check out the release plan:

Build 41 Preview and some bug fixes

I'm back from GDC and wanted to get this build out to you quickly with a few bug fixes that we introduced in Build 40 and also talk about what you can expect to see in Build 41.

  • Procedural Level Generation will be a primary focus. The goal is to have more variety to the missions and less square shaped levels.
  • We're going to take a shot at cleaning up some cover issues and introduce a "Step out and fire" mechanic when behind a wall.
  • Ambient Sound Work.
  • New Grenade Sprites and icons

As always, you can read the entire post on our DevLog on itch.io:
