We added it so that people can personalize their avatar and even have 2 people with the same character look different. It's for the community to make cool new stuff. I personally can't wait till the community starts making stuff for the characters, alot of really awesome things can come out of this.
Okay, so exactly how is that working? Like, are we gonna just get all the stuff to start or will there be unlockable items for each character? Like surviving on a certain difficulty on whatever map or leveling up a certain perk to a different level? I mean, personally I feel that it would be pretty cool to have more incentive to playing on Hell on Earth (other than its the most brutal, butt-clenching experience since playing Sweet Home on the NES) or leveling up perks I normally would not use.
Also, since there is already character customization, is there a possibility that weapon skins will be expanded upon in KF2? You guys did release the Camo and Gold packs for weapons, so why not also add unlockable weapon skins? (plus, considering the weapons come from a 3d printer, it would make sense to have skin variants)
Of course, if you guys did release these things as DLC, I'll buy the hell out of them, I'm just one of those people who enjoys the feeling of accomplishment and having physical proof to gloat with. Hence me only using Commando Chicken. I don't care who or what likes it, he was the coolest of the bunch next to Foster and Skully.
