For a long time, basic crit chance stacked multiplicatively. It's only some time around 2.6 they chance it to stack additively.

As for special crit, I think it always stacked additively, but it is hard to tell since crit chance on gear is much lower, so the only real source is Animated Batman Beyond's passive.
