As soon as both are assigned, activate the quitting bell to summon any other settlers. Once the first is assigned, simply find another person and do the same with the second arena pad. Once these are all built, find a settler or companion and assign them to one of the two arena pads with. The bell will need to be powered, so construct a power source too if you don't have one nearby. Build a red and blue arena pad relatively close to each other, and then place a quitting bell nearby. Find some empty space in a settlement that has several settlers or companions, and enter the workshop menu. This is by far the easiest achievement of the 3, and simply requires you to pit two settlers against each other in a hastily built arena.

I mentioned in the general hints and tips to grab food when possible, and cook it for XP and health. This will save time when it comes to working on this DLC. I've listed the food required below, but as recommended above, it might be worth playing the regular game for a while and just hoarding these when you come across them. If you haven't already grabbed the copy of Wasteland Survival Guide from Sunshine Tidings Co-op (directly west of Lexington, by the map edge), now's the time to do it, as it will allow you to collect more meat from killed animals.
To unlock all achievements in this DLC, you will need Charisma at level 9 and the perks Animal Friend and Wasteland Whisperer at the 1st rank.That way you don't waste the level up points or resources required for these achievements. For that reason I recommend creating a master save, and then reloading this once done with the achievements. The quickest and most straightforward method to the 3 achievements is not the most aesthetic or organized when it comes to your actual settlements.First though, a couple of tips to make this DLC easier: Because Wasteland Workshop does not have quests as such, I will divide this walkthrough by achievement.
