Medium badge: Lab- Medium - stay around the lower left corner. Get the Grenade Dart Launcher and the Pancor Jackhammer. For each wave, hide in the lower left till you have 100% HP, then jump up and use the grenade launcher to get a headshot (usually a midair headshot, and as they spawn more per round you get double and triple kills. Make sure to stay up there till they're dead else you dont get the points. Use the jackhammer for anyone who follows you down or spawns behind you. Got me to over 300 kills and then I got bored.
Yet another pay-to-badge. Over an hour to pass the first door? 0/5 you should be ashamed of yourself. I don't mind paying for a game that's fun. Paying for a grind is never going to happena
I watched an ad to speed up all quests and it didnt work at all. Rating has been reduced to 1/5 and I will not watch another until there is independent assurance that the system actually works.
For being infected with hypotonia, kidney failure, ataxia, and diarrhea, humanity is surprisingly resilient. Really wish I could get the hard badge for killing everyone on realistic. Took me till April 30th 2009 to kill everyone.
