I actually solo Project Paradise pretty regularly. I tend to spend four minutes filling up the toxic sludge, two minutes filling up the venison, and ignoring the radkelp. The bloodbug that spawns dies almost instantly, the Giant Sloth survives to round 2 (sometimes survives the whole match if it wanders near me), and I follow the Deathclaw around killing everything that gets near it and spamming it with my medic gun when it gets low. When the Alpha shows up I make sure to put myself between it and the Deathclaw and just auto axe it down.

I've soloed every event now and the hardest one has to be Radiation Rumble, the only way I've found is to be in the tunnel as it starts, grab 10 ore ASAP and spend the rest of the time babysitting. Solo Eviction Notice is surprisingly comfy, simply sit on the generator and kill everything that waddles up to you.

Anyway it was the top of the hour and we just got a good turnout to see a robot marry a bucket for the 5,000th time.

I think the only thing in Fallout 76 that a human being absolutely cannot do solo is Raid stage 2. Bizarrely, I feel like stage 4 is EASIER solo, although extra hands are always welcome for 1, 3 and 5.
