You will need at least a buddy to do this trophy. Invite your boosting buddy to an infestation match and make sure the difficulty is set on hard or insane. Either let the bugs knock you down or kill yourself with the rocket launcher/remote charges and start the reviving.
Take note though, you can only get knocked down so many times in a round. If you go past what the game allows you (it shows how many lives you have on the screen) then you die and cannot finish the round. So always make sure you have one life left and finish the wave. Rinse and repeat until you and your friend have 25 revives.
