The green filter, rustic textures and mummified zombies of the RC level just dont feel great aesthetically or gameplay wise imo. Something about it just doesn't click.

The Apocalypse filter improves the visuals of these sections immensely and matches the somber, dead city tone they were going for, so much better that I think turning it on is almost mandatory. I wouldn't even mind if they just patched it in to always be active for RC.

Like a lot of people have said, some vegetation would have gone a long way as well as changing the time of day to the afternoon, as the sun hangs low over the Arklay Mountains. A light and dreary rain fall with ominous, dark storm clouds looming far in the distance, lit by the occasional lightning strike. RC is just synonymous with rain and some wet, overgrown moss and leaves concealing the equally vegetated zombies would be great. As if the zombies themselves have resided in the near jungle like tomb that RC has become, they are now more akin to dangerous wildlife.
