I got 4 out of 7 at the start (i have the game 126% completed, only the one "gone in 30 seconds" is missing to get 130%)
Stench - dont get it at start... with 126% completed, but after playing a levle i got it, so a lil replay is needed to get this one. Head hunter - solved when i started the game Veteran - solved when i started the game Industrious - solved when i started the game Huner - solved when i started the game Thrift-Box - dont get it at start, my best score is nearly 50k, but i get it after i completed a levle with 5k score, so here a lil replaying is need too. Railgun Shot - i dont get it at start, im too lazy to test out if another replay is needed to get it. maybe ill try it later.
Sorry, lil misunderstanding maybe, my post was not a "moaning and groaning" one, it is just a lil advise for other players (and im not too lazy...^^)
All in all a lil "re-solving" is needed to get some of the quests. I got the 7th one now, by re-solving it too. So for "Stench", "Thrift-Box" and "Railgun Shot" a re-solving is needed... not a big deal.
Shotgun, Browning, M-60... with these three it is possible (minimum, maybe with others too), just look out for a big cluster of zombies and then... good luck, you may need some trys, but sooner or later...^^
wat if one wants to earn bullseye later in game? the background in killer and selectoner levels have a different background, how to get the background needed for bullseye back?
For "Zombieball" in the "Just do it" achievement, does it need to be a 5 star enrage? I've gotten in to an enrage for a few seconds 3 or 4 times, and I still don't get the achievement.
