With the release of the store there are new items that are available for micro-transation purchase only. They are Key Locker, Beacon, and Portal Frackers.
What are they used for and how can I get them?
For those of you who don't have the store yet, it's coming in an incremental rollout.
Best Answer
These 3 items can only be brought from the Ingress store. At this stage they are unobtainable from hacking. I will list the items and go through their uses below.
Key Locker
Beacon
Portal Fracker
Strategies:
If you have lots of keys in your inventory, maybe invest in some Key Lockers. They function just like regular capsules, so you can sort the keys in there by distance or title.
Beacon's might be useful for new players but don't seem to hold any value that good team communication doesn't already provide.
Frackers would be useful for flash-farms where agents are very low on gear. But to make the most of it, there would need to be VRMH, VRHS deployed, so that agents get more than 3 hacks in 10 minutes. Also, to hit 150 hacks with a single VRHS on a portal, you would need 25 agents in the same place. Multiple VRHS's deployed would allow hacking faster than 90 seconds. The usefulness of this item depends heavily on the availability of standing farms in your area.
