Ok, I kept seeing dudes run over the same spot where I saw a drop and figured they were getting the same stuff. I guess it makes sense that if I’m level 10 and you’re level 20 you’d have higher-level gear showing up.
Either way, I managed to get through a bunch of the “strike” missions without having to actually talk to anyone or worry about being online at a certain time. Most of the time I just hung out in the “patrol” zones and teamed up with nearby players whenever a walker or something spawned.
