Tried to use all the weapons in the game. still no quest :/
Also, I noticed something: when starting a new game, there are 8 weapons that are locked/have to be bought (MAC-10, Shotgun, AK-47, Sawn-off, Magnum, Stun Grenade, Mine and Molotov)
and my quest is "88% complete". 88% is 8/9, and I bought 8 weapons, maybe the quest "thinks" it should be unlocked only if you have bought 9 weapons, which is impossible. perhaps this is the problem?
I guess I should call @MrDayCee to take a look at it
The Quest should unlock normally @armorplayergc ... have you tried playing with different combinations as well? I unlocked it when I bought and selected the Magnum for the level that requires use of this gun. To give an example...
how do i get Completionist! achievement I have already 45/45 stars.. i already restart it and finish the game again! i didnt get the last achievement! some players experience it too.. is this a bug please fix it!
This comment by "Savdog" made me get the fearful level 9 on second try:
You need mines and molotov at max level. You should also have most stars/buffs already (I had everything except Thorns maxed). Then when you are throwing the mines, put them both in the same place (in the middle of a zombie pack). Same with the molotov. Double mines or double molotovs is enough to cut through the regeneration of most zombies. Your primary weapon is only for cleaning up anything else that makes it through, so go with whichever weapon you like. I used a maxed sawn-off.
As long as you're good at aiming you should be able to handle the big packs that come through. Good luck!
