Playstation 4 graphical downgrade confirmed.
PS4 missing graphical effects:
-Dirty lens flare is completely removed
-Lighting effects are dulled on walls, more monotone overall
-Some missing Shader textures on Zombies
-Missing Particle effects, debris, birds in the backgrounds and missing in entire sections of the game.
Besides the graphics being downgraded, the game is also completely missing any multiplayer mode, local or online. This game is looking more and more like just a cheap cash-in by Ubisoft.
