What I'm requesting from the community.

Please post below when you find the ids of the weapons with valuable camos. All guns with different attachments and camo have different id than the base. I'am doing this to help people find dark matter, diamond ,and gold camo for zombies. Please post what map the camo is for as well. This thread will be updated every Friday at 11:30 PST. Feel free to take this down if pudpud09 or anyone else in the community is negatively affected by this.
