it may be lag... because i have the fire retro but i dont know how i've unlocked it...

Boosting.

whats the fastest way to boost for this? Private match?

Private match, KOTH, 240 points to win, fill with casual bots.

do the bots take the hill or do they ignore it?

They'll take it, but you can break it easy.
If you actually go for the objectives, you should still get 50-60 kills per round.
Set the number of rounds to max, and you'll get ~700 kills per match.

what you need for golden hunter ?
probably kids boosted if you need matches/kills
