So me and my girlfrend like to go to my villa with our laptops, light up the fire, pour whiskey in our glasses and play killing floor and have sex for the whole weekend. The problem is that there is no internet there so we play on LAN and we don't level up nor win any achievements during our offline play. It is not a problem for me because I am almost lvl6 at any perk but she wants to level and we mostly play there so is there a way to make the game level up when you play without internet connection? We don't want to cheat or anything just to be able to level up when we play offline ...
