Luckily, I got in touch with ZombieDyer, also a ForgeHub member (can't tag him for some reason). He says he's got a group of (mature) friends who's hosting an Infection lobby on Saturday. So I'm hopeful I'll get some good testing going. It's a shame to hear the game is mostly dead in terms of custom games, though. And @Buddy Jumps I would definitely appreciate that! Here's a sneak preview of my upcoming map, in the hopes of getting some of you to give this game another try...
Check out my map. UNSC Savannah. It’s a linear infection map. I’m super proud of it. Every thing works well. I have buttons to unlock a huge gun at the end. One in each area. A huge grav lift. Lots of orange stuff. Everything you could want.
