When the Corrupted Crew reaches 6-12 Tactics, you must resolve Corrupted Tactics effects, as shown on the Solo Tactics Aid card.
You must, twice, discard 1 Hidden Influence card and then gain Influence with the corresponding House. You must select a card with a House whose track you can advance on. If you don’t have 2 such cards, you may discard less.
Example (Mind Reading): You discard a Shiveus and Yarvek Hidden Influence card, and move up one step on both corresponding Influence tracks. On the Yarvek track you reach a Discovery Data cube and gain it immediately.
Reveal 1 card from the Hidden Influence deck (not the Corrupted House deck) and the Corrupted Crew gains Influence with the House on this card. Then discard the card.
Place a Shield on each ship owned by the House that the Corrupted Crew has the highest Influence with (if tied, the leftmost on the Influence board). This will protect the ship as explained in the Solo Skirmish Phase.
