Haven't been keeping this devlog up to date, so there's a lot of new stuff. First up, there's now bots for multiplayer (including co op) and a new level:
With some new bosses:
And a new campaign map screen for selecting them:
Also got a lot of steam integration stuff done, like joining multiplayer games through your friends list and using steam cloud saves. Plus plenty of new enemies/weapons, and some balance tweaks and graphical improvements (check out the new player engine trails in the screenshots).
Man, I'm speechless what a great and fun looking game! I was planning on making something very much alike to what you have here, but then I saw your game. WOW, I mean, I won't even dare. Great job, definitely on my wishlist.
Definitely worth giving it a try, plus I'd be happy to answer questions if there's something in particular you want to know how to do.
