-When a player dies, their name will grey out in the upper left corner.   When all other players are dead, you win the round.  First to four wins the match.

Strategy:
-Hiding in a 1v1 is usually the better choice.

-Try to pick off opponents near powerups and then grab them for yourself.  Get a kill and then use a stealth powerup to fade back into the crowd.
-Some combat powerups like shotgun and rapid fire have insane power.  Prioritize getting them at all costs.
