Can we compile a list of version differences for reference?

-uses Gamepad screen and touchpad for lockpicking, all item management, and scanner. All other versions have this information displayed in the HUD.

-Darker environments in comparison to the ports. "Dirty lens" filter not present on PC or PS4.

-Miiverse integration for high score leaderboards, spray can messages, and zombies of dead players. These zombies have BOBs that can be looted for whatever was left behind. If you encounter a former survivor with lots of ammo and health items in their bag, it can greatly affect the run.

-Slower load times?

If anyone has more info, feel free to post it!

Edit1: It seems like PC has the ability to skip the intro and most of every "traveling" cutscene. On Wiiu, traveling cutscenes can also be skipped, but you have to watch 90% of it anyway so its not very useful.

PC and PS4 have different melee weapons that you can pick up. These include a shovel that is located next to the crate where you find the Lockpick, and a nailed bat that is located just before the trash chute in Ron's Flat. The Shovel can hit multiple enemies while the Nailed Bat has increased potential for critical hits.

PC seems to have strange physics glitches. I observed some zombie lunges that missed the player at point blank range.

As far as movement goes, I think your character moves faster in the PC port. Turning can also be instantaneous due to mouse controls.This is impossible on WiiU.

Rate of attack for melee weapons is much slower on WiiU than PC. I observed bat swings to be very quick compared to WiiU, where your character seems more slow and sluggish the more you use it.

Lastly, I want to say load times are different but I need someone with PC or PS4 to confirm.
