Pokerstars have introduced bounty tournaments.  Knockout a player and instantly receive some cash each time.  Collect as many bounties as you can.

They have started off with 9-seater knockouts and 90-seater knockouts both at a wide range of buy-in levels.  There are also Heads-up MTTs with knockout bounties

As an example there are $13.50 90-seaters with first prize of $247.95 and second prize of $166.50, etc, down to 12th prize of $22.50.   For every person you knock out you will collect a $2.50 bounty

As a 2nd example there are $27 90-seaters with first prize of $495.90 and second prize of $333.00 down to 12th prize of $44.10.   Each knockout bounty is worth $5 in this case.
