DICE TeamOk, so I played, won the first match, completed all challenges a few hours after. What I've learned from this mode is that I'm usually the last to die, as I only got to respawn once.
Thing is, it doesn't feel different from the normal Apex at all. I guess the main reason for this is because players don't know how to take advantage of the free respawns, they either quit shortly after dying or stick too close to the teammates, fighting till the last one dies. Nobody seems to understand that chickening out to make it alive to the next round saves the team.
