Once Human - The Wondering Bus: Great source for Acid, random resources, and XP

The Wonderer in Once Human is much more than a wondering bus that creepily patrols the roadways of the Once Human landscape. It is a once-daily loot drop, that you can claim by jumping inside while it is near the ground. It can also be a small but good resource farm for things like Acid which is needed for crafting some metals and medicines. Simply attack the bus focusing on the legs and feet because the body is immune. When it lowers near the ground it will spawn multiple bad guys, quickly eliminate them and you can often bring the bus back down to drop more, with it never really moving. How long you can do this is a bit random but I've had it work for 10 minutes before or 30 minutes. Once I was ready to stop and collect but the enemies wouldn't stop spawning and chasing me even I moved fairly far away. Occasionally though you can take out all of the enemies and it will move on regardless, so I haven't gotten that part down to science yet.
