i dl’d the project unpacked it, start no go re-compiled then go, i used ue4.10.2 vs2015
had a quick look, sorry didn’t get much time this weekend, my main issue which you might be able to help with is changing the project/game name. i have the same issue with the shooter demo i can add it to a named project but the compiled game is still called ShooterDemo i expect yours does the same.
apart from that it looks very interesting, i just need time to start pluging things together and getting some custom content working
