It's hard to explain, I've seen some posted before, I never understood them and I don't really know what keywords to use to search (apart from "bit array" but I didn't really find anything) I may as well ask while it's on topic!

It's an extension of storing 32 bools in one variable - it stores 32*x bools in an array. When reading bits 1-32, the first cell is used, 32-64 second cell, etc. So for example, slot 123 would be the 27th bit in bit_array[3].

Yes, they're what you've seen in some IsThisASomething. One HUGE example is g_baValidModels in hold-studio.pwn. For readability, I used binary notation instead of numbers or hex.
