Skullmining is a Proving Ground Project in XCOM 2.
In-Game Description[]
“ | As if the Skulljack itself wasn't invasive enough, Tygan has conceived of a more thorough means of extracting information from ADVENT soldiers' chips. This new "Skullmining" technique could lead to new intel gains from our enemies, and could even grant access to hidden Alien facilities for the purpose of sabotage. I can also upgrade our Skulljacks to significantly enhance the hacking capability of any soldier carrying one. | ” |
Project Effects[]
Improves the Skulljack: Allows soldiers to Skullmine ADVENT soldiers. Also increases the Hack stat of a soldier carrying one by +25.
Skullmining: Soldiers can hack into the chip in ADVENT soldiers, granting a possibility of obtaining Intel or Avatar facility locations. The chance of success increases with the soldier's Hack stat. However, it should be noted that if the hack fails, your soldier will take 3-4 feedback damage (and 3-4 additional damage every time the unit tries a hack or uses haywire protocol). All enemy soldiers suitable for Skullmining have a Hack Defense rating of 125.
Note that the equipped GREMLIN's hack bonus does not apply to Skulljack hacking.
