We have some exciting news to bring you now, as we’re guessing not everyone is aware of this. In Call of Duty: Black Ops zombie mode, upgrading the Ballistic Knife with the pack-a-punch machine offers more than just enhanced damage.
We can tell you that upgrading that knife will produce a weapon called the Krause Refibrillator, which will allow you to revive your team mates from distance! As you know, the standard Ballistic Knife allows you to shoot darts from a distance, but the upgraded version will turn those darts into revive darts! – a very nice idea from Treyarch.

Of course, you’ll still have to have the skill to aim the upgraded dart towards your ally, but doing it correctly will bring him/her back to life instantly. We’ve found a video below which shows you how the process works, you’ll also get a secret trophy/achievement called ‘See Me, Stab Me, Heal Me’.
Try and revive your team mates with the Krause Refibrillator and let us know you get on with it. Do you find it easy to use? Don’t forget about our tips to kill the Pentagon Thief on the Five map.
