I haven’t given up on https://forums.epicgames.com/showthread.php?970055-Shoot-Em-Up-Prototype-quot-Grazer-quot, it looks much better now (last added feature was custom online multiplayer with the lockstep method) but it’s still about a year away from being finished as I haven’t been able to focus on it properly, I really hope there won’t be any trouble with releasing UDK games in 2017 and later.
