PCC and custom games works too!
BTW: The bounty trophy was glitched too, but now it's fixed!
GOT the "Bounty Hunter" trophy! Long story short: You need to play 50 games (with 1 bounty atleast ofc) because you "collect the bounties" on the results screen, after the game ends. So the req. is not "eliminate 50 players in bounty game modes" or "eliminate players 50 times/with hands". I eliminated 120+ players with 70+ hands, since the patch, but these doesn't trigger the trophy. So the trophy is now obtainable, thanks for the fix!
BTW: I still tink the "Keep Your Heads Up" trophy glitched. No way I'm not played 100 h2h games already since day1. Just today I played 31 already. And I played A LOT of "mano a mano" in PCC too for testing/farming the trophy since release. I know a severeal players have the trophy/achievement across all platforms, but something wrong (atleast with my game). Please trophy/achievement hunters, test it, thanks! And as always, sorry for my english!
