As much as I want to put a positive review, I can't. For me, Icarus is most fun with friends and with this error #028 / p2p network error, I can't play with any of my friends, vise versa with one another. I remember this being an issue with the games release, we stopped playing, came back a couple years later, and it was great (where most of my hours came in), now after coming back almost a year later again, we can't stay on the same server for more than 5 minutes without getting this error. Any fix we've looked up doesn't work, and there's otherwise no help from staff from what I could find. When this is fixed I'll update my review but so far this is the only game I've ever had this issue is so prevalent on.

I'm sorry to hear about your experience with Icarus. It's frustrating when technical issues prevent you from enjoying a game with friends. Hopefully, the developers address this error soon so you can get back to playing together seamlessly. Hang in there!
