Due to the high likelihood of receiving duplicate item drops, this group was formed to bring collectors together. Being able to trade away duplicate items makes collecting each item way faster for everyone involved.

This group is public so please invite all your friends that are interested in collecting all drops! The more the merrier!

1. Subscribe to this workshop map
   
2. Play that map offline on classic. If you haven't received a drop in the past 45 minutes and haven't received 3 in the past 24 hours, you will have received a drop at the end of that game. Note the time at the end of the game. (i.e. 12:00 noon)
   
3. 45 minutes after the time you noted above (i.e. 12:45), repeat Step 2
   
4. 45 minutes after your second game, repeat Step 2 one more time.
   
5. On the next day, remember you got your first drop at 12:00 noon on the previous day so you can get today's first drop at 12:01 so plan the start of today's gaming accordingly (like start your first game a minute later than you did yesterday). This is important to note. It doesn't just reset at midnight <some timezone>, so you can't just play at the same time every day to get your drops. It is a rolling 24 hour window so basically it just makes sure you haven't received a drop in the last 45 minutes and haven't received 3 drops in the last 24 hours. If both of those conditions are true, you get a drop, yay!

NB: AFAIK the game needs to run some amount of time (25 minutes has been suggested, credit goes to Tolly) between drops. I normally have my game just idling on the menu screen which solves that problem.

* "Fastest" in this case means it wastes the least amount of your time, however you are still limited to 3 per day and at most 1 every 45 minutes.

Video Explaining The Process

1. On your profile, click "Edit Profile"
   
2. Click "Privacy Settings"
   
3. Your Inventory must be set to "Public" or "Friends Only". If set to "Friends Only" you must friend someone before you trade with them. I wouldn't recommend this since it's just extra work for every trade but it's one path you can take. If you set it to "Public", continue to step 4.
   
4. Go to your Inventory
   
5. Click "Trade Offers"
   
6. Click "Who can send me Trade Offers?"
   
7. Click "Create New URL"
   
8. Either share that URL in a post in the trade group page OR post it somewhere in your profile and broadcast to the group your proposed trade.

If you made your inventory "Friends Only", after friending someone, access their profile and click the down arrow to the right of the "Message" button and click "Offer a Trade..."
