Okay here is the list of what I know you can hack:Guns on WallWindowsPerk MachinesDoorsTeammatesTerminals and Button on Wall(for the achievement)Mystery BoxPack a PunchExcavator ControlsDid I miss anything? If I did, please tell me what it does when you hack it.
I Dont think you can hack perks and mystery box,but i think thats everything
(Guns on Wall) switches the regular ammo with the upgraded ammo price so 500 points for upgraded and 4500 points for regular ammo (Windows) normally you only 60 points from fixing a window if it is completely broke but if you hack it to fix it. It gives you a 100 points even if it is only one board that's broke (Doors) when using the hack all cost only 200 points but take a long time to hack (Teammates) you give them 500 points to the person that your hacking (Terminals and Button on Wall) for the achievements (Pack a Punch) but only to close in the fence or cage if you prefer around the pack a punch last for a while but I strongly recommend you should release a Gersch Device or if you prefer black hole bomb just before the cage opens to get out of there (Excavator Controls) for achievement and to stop the circle blades in the tunnels and in the bio dome I think that's all of them but you never know
Steve has about answered everything; except you cannot hack Semtax Grenades, Claymores, or Bowie Knife. However you can in fact hack Mystery Boxes when the boxes are not there... What I mean is that you cannot hack the actual mystery box itself but the other three possible locations with a teddy bear can be hacked for 1200. When hacked, they will give you a turn at box and also keep that specific location from being active for a while.... Meaning that the box will not move to that spot for a while nor will you be able to access the box you hacked with either a hacking device or even during a fire sale for quite some time... Could be quite useful to hack the box in receiving area near quick revive and the one near power to keep the box near Mule Kick and the Dome because those are the best areas in the map to run with 2-4 players. Also you can hack perks back for a refund of price... Best strategy for getting the Perks in Space achievement. (Buying all 8 perks in one game) Also it's wise to hack back your perks before you complete the easter egg and get 8 permanent perks so that you get all your money back. (Which can in turn be used for upgrading 3 guns for the Fully Armed and Operational achievement.) Also the One Giant Leap achievement is best to get after you complete the Easter Egg so that you can be revived with 8 perks and just go through teleporter and pack your Mustang and Sally... ;-) ) Just remember to buy all 8 perks before you complete the Easter Egg and get 8 permanent perks because once you do the Egg you cannot buy any more perks to complete the Perks in Space achievement.
