You can follow his Twitch here
According to Scan, his Terran Guide Pack includes:
"8 videos of TvP, 3 videos of TvT, 4 videos of TvZ, totaling 15 videos... If you are interested in improving your Terran skills and knowledge, you should definitely buy it! It is covered with explanation in Korean language, but you will understand and figure it out easily with the small details I'm showing on the screen"
This offer only costs $12. I believe Scan is offering it cheaper than he could in order to sell it to more people.
Payment method: Direct PayPal transaction.
Payment type: Friends and Family, and then he will give you access to download the guide pack via his Google Drive.
If you're interested or if you have questions, you can contact Scan via Discord (Scan #5181) or join his Discord Server
Please consider supporting Scan and your own Terran skills by buying this pack. If you play another race (Protoss or Zerg), you might also benefit from it.
