When I first went Topside in Arc Raiders, I was convinced that it would go down similarly to Tarkov: no talking, just fighting. But I was pleasantly surprised when I found this to not be the case at all.
Arc Raiders has managed to find itself in a sweet spot for PvPvE where a shared hatred of arcs and greed for their loot binds strangers together, resulting in some truly brilliant cooperative plays. Something that the devs weren't 100% sure they'd see.
