Yeah, it started out as EU4 but I guess with Sony's backing they were able to transition over everything. Definitely one of the most smoothest and polished online experiences I've had in years. I think the only issue I ever ran into was once during the Beta with a Memory leak which required a hard restart for the console.I didnt know it was unreal engine. Yes felt smooth, fast, stable and plenty shooting mechanics all done well
Oh and Lark spores would definitely mess with the framerate just a little if an area was spammed with them lol.
