You have just conquered a Data node. Sometimes you do this to accomplish a shadowrun. But, most likely, you are just hunting for some files to sell for nuyen.
Accomplishing a matrix shadowrunEdit
For shadowrun targeting Data node, you'll get a passcode and a "Recog code" from Johnson. For "Upload file" shadowrun, you'll get file to upload as well. All these things Johnsons provide don't occupy any storage of your deck. However, for "Download file" shadowrun, you'll need to reserve some storage for the file.
You'll need to use "Erase" or "Tansfer Data" function. Using any function may yield "You failed to operate the node successfully!". As soon as you succeed in using a function, you have no risk: reliable "recog code" will do its job, immediately locate the file you need. For "Download file", you'll need deck storage (see below).
One of three types of actions is required to accomplish a shadowrun targeting a DATA node:
1. "Delete file". Straightforward way is to use "Erase" function. As soon as you activate "Erase" function, "recog code" provided by Johnson will instantly locate the target file and delete it. You don't need free deck storage for this shadowrun. Interestingly, the game has a bug that makes "Delete file" shadowrun equivalent to "Download file". If you "Transfer Data" instead of "Erase", the "recog code" will locate "Back-up Files". Downloading this will accomplish shadowrun as well. However, this way you'll need deck storage for the file, and you can't sell it to Roscoe. See "Download file" for details.
2. "Upload file". Use "Transfer Data" function. "Recog code" will do the job. You don't need deck storage for this action.
3. "Download file". Use "Transfer Data". "Recog code" will locate the file and prompt you for download. All you need is to confirm. You'll need up to 30 Mp of free deck storage, and one free file slot. For particular "Download file" shadowrun, file size is 10 Mp, 20 Mp, or 30 Mp, with equal probability. As soon as you get the file, the shadowrun is accomplished. The file you get is encrypted and you can't sell it to Roscoe afterwards. However, you may delete it from your deck as soon as you get it, the shadowrun will stay accomplished, then you may go on harvesting the data store.
Harvesting the data storeEdit
When you use "Transfer Data" function, the following happens:
1. If you are on a shadowrun, and this node contains the target file, a "recog code" will find it. If this node is targeted by your shadowrun, you can't get anything else from this data node until you accomplish the shadowrun.
2. You "find an interesting file that you download to your notebook", if this node contains any. These will add to "Tips & Clues" and help you progress through the game. You don't need deck storage for them. Some "interesting files" are available only if you have enough criminal records :-). One node may contain more than one "interesting file" at once. You can't harvest node for files until you pull out all "interesting files" available for you now at this node.
3. You harvest the node for files to sell them to Roscoe afterwards.
So, let's suppose you have advanced over 1 and 2 and are harvesting now. Harvesting node is a random process. The chance that you find some file using "Transfer Data" once is calculated by the following formula:
chance = 10% * round_down( (attr_intelligence + skill_computer + deck_sensor) / 3 )
Thus, if your Intelligence attribute is 6, Computer skill is 12, and Deck sensor level is 12, your chance to find something is 100% :-)
As you see, you should raise the stats sum at least +3 for changes to take effect. Effective way to improve harvesting is to upgrade your deck_sensor, as you only need nuyen for that, which is less deficit than Karma. Also, raising intelligence takes less Karma, than computer skill.
As usual, you have a chance to "fail to operate the node successfully" each time you use a function, as well as activate alert or be kicked from the system afterwards. Most likely you'll repeat "Transfer Data" continiously, until you are either kicked out from the system, or all your 5 file slots are filled.
When you find something, the file name, file size and file price per 1 Mp are determined. You may see the name and size of the file, but you can't peek the price of a file until you show it to Roscoe.
File name depends on the topic of the data node, but it doesn't affect the price of the file.
The size of the file you find may be 20 Mp, 30 Mp, 40 Mp, 50 Mp, or 60 Mp, with equal probability. Thus, it is good idea to have 300 Mp of storage reserved for harvesting. The price of the file is proportional to its size.
The color of the node is the only thing that affects the price. All Blue node files are worthless. Don't waste your storage on Blue files.
Chances to get particular price per 1 Mp are represented in a table below:
Chance Price Price Price (Green) (Orange) (Red) 14/42 = 33.3% 0 0 0 2/42 = 4.8% 5 10 25 5/42 = 11.9% 10 20 50 3/42 = 7.1% 15 30 75 5/42 = 11.9% 20 40 100 6/42 = 14.3% 25 50 125 4/42 = 9.5% 30 60 150 3/42 = 7.1% 40 80 200
Each third file is worthless. The mean price of 1 Mp of Green node file is 14.17 nuyen. Orange node files are twice (2x) as valuable as Green onces, and Red node files are five times (5x) as valuable as Green ones.
The maximum possible sell price of a file is 12000 nuyen. And the mean gain for 5 harvested files is about 2800 nuyen for Green node.
As you see, it is reasonable to get rid of Orange and especially Green files if you hacked into the Red storage. Also, you may want to delete smaller files to free a slot for larger one.
