"Mooching" as Ada works nicely as long as you intersect, but if that fails it's just like playing as Leon/Helena. Just be sure you run to the elevator after the fight, otherwise it won't save the kill.
I'd like to recommend joining random games as Helena too, but you might end up wasting your time as it seems some people under "Here For Events" don't realize you can skip right to the fight.
Got 100% on the scratch card today and got Ooze (Chunk). Weak.
