Well fellas, you all know I am an achievement whore. I 100%ed KF2 last night. Was having troubles with groups doing the DieSector endless wave 25. Just soloed it instead. Much easier due to the weaker zeds when you're solo.
The game naturally doesn't show as 100% due to the new maps being on the radar for achievements, but for the moment I am complete. Although this does leave my wife as still needing that one last map for endless HoE (as well as a ton of perk leveling to do). I am trying to train her to be a badass now. =)
I will still be on KF2 here and there to play with those who prefer to play with people and my other friends who have many maps to go. I doubt I will do any perk prestige-ing when that comes out. I just don't care enough. Feel free to invite me to whatever if you feel like though.
I still have most of KF1 to do HoE for. A far more challenging game, albeit less fun than 2.
