In Left 4 Dead, if the enemy team is ridiculously bad, my team may initiate death race rules to spice things up a bit. Basically it’s just run as far as you can without looking back—every survivor for him or herself. You can save people if you really want to, but not if you have to move back to do so (only if the target is within range while looking back, or up ahead). That being said, if someone is particularly close to me in the race and gets pounced, I might take a bit of time off from running to wait until they’re incapped to kill the hunter, teabag them a bit, and then continue my journey.
Obviously the winner is whoever makes it the furthest.
