(adsbygoogle = window.adsbygoogle || []).push({}); Alright, I have now played several games, in which I used hacker in several ways. I was really surprised at how useful it can be.

What I definitely know:

1. Hacking a gun - switches the price of regular ammo and upgraded ammo. For example, if you hack an MP5K, the cost of upgraded ammo becomes 500 points, and the cost of regular ammo becomes 4,500 points.
2. Hacking the Pack-a-Punch machine - this will give you 1,000 points, and will close the gates all around the Pack-a-Punch machine. No zombies can get in, and you are safe to Pack-a-Punch your guns. You can shoot the zombies through the fence, so free points.
3. Hacking a door - this will decrease the cost of any door to 200 points. WARNING: This take 30+ seconds. Only do it if you have a crawler or if you are being protected by your teammates.
4. Hacking excavator controls - there are three excavators in the room with Quick Revive. You will hear a lady announce that a Excavator has been breached, and you have a certain amount of time to go to the controls and hack it. This will give you 1,000 points, and will keep the tunnel that it was for opened. If you do not do this, the tunnel it is connected to WILL be blocked. Any attempt to go through it will NOT work, and it is an instant death. Strongly suggest you hack these when it is announced.
5. Hacking a teammate - you can face a teammate, and can hack him/her, too! What this will do is it will take 500 of your points, and transfer them over to the other person. Can be extremely useful if one person has a ton of points, and another needs only a few more to get Juggernaut, or the box.
6. Easter egg - the hacker is used in the Easter egg, so look up a tutorial on it.


What I was told by friends:

1. Hacking a Perk-a-Cola machine - you can only hack the Perk-a-Cola machine that you already bought. Upon hacking, you lose that perk. This can be used to get the achievement that requires you to get all the perks. I do not know whether you are refunded the points you used to buy it.
2. Hacking a power-up - a power-up can apparently be hacked, according to a friend. When you hack a power-up, it will change to a MAX AMMO 100% of the time.

yeah u can hack a power up for sure and it turns to max ammo and u can do it again to turn it into a firesale
