The engine is the only hope this game has to stand up again, it's a fact, you're pretty much in denial if you think otherwise. The main objective of this engine is to give developers an easier time with coding so new content is released more easily, fixing bugs and above all give better optimization to our modern hardware. etc. The current engine of APB is a mess, it's a beta version of unreal engine scrapped and taped together, it's overly saturated with messy coding, whenever developers try to fix a minor bug, they end up breaking the whole game entirely.
If somehow LO manage to make this game perform as well or similar as e-sports titles like CSGO, Dota 2, League of Legends, etc which are fairly easy to run games on respectable hardware, then APB can AT LEAST bring back the old numbers it used to 6 years ago
