Similar to the one in Giza, the Sukhothai map in Indiana Jones And The Great Circle features four radio frequency cards tucked away in hidden spots. Players can grab these cards soon after arriving, provided they’re ready to navigate through some heavily guarded areas. Collecting all four cards will lead you to secret stashes filled with cash.
Obtaining the Royal Army Transmissions is a fantastic way to get oriented in Sukhothai. This will allow you to explore the northern part of the map while getting accustomed to traveling by boat with Gina. The camps you infiltrate also contain extra supplies if you’re up for the challenge.
Voss’ Camp
Your first mission in Sukhothai involves raiding Voss’ camp to retrieve his gold reserves. While you’re there, be sure to check out the large map room located on the first floor of his office. In the northwest corner, you’ll find a bulletin board. To its right is a table equipped with a radio and typewriter; the first frequency card can be found on this table.
Wat Chana Songkhram
At the army camp located at Wat Chana Songkhram, which is situated just northwest of the village, there’s another radio frequency card that’s easy to reach if you can avoid the guards. It’s best to approach from the south; the card is located inside the guardhouse on the left as you enter.
Be cautious as there are two guards stationed at the entrance, one in the tower above, and dogs patrolling the inside. If you’re not wearing a Royal Army Uniform, it might be a good idea to sneak in and take out the guards first.
Wat Chana Songkhram is also where you’ll find the Timely Arrival Mystery, offering additional rewards if you linger to solve that puzzle as well.
Wat Sa Si
Wat Sa Si is located near the northwest corner of the map, with the army’s radio tent situated at the rear of the camp. The best way to enter without confrontation is to dock at the southeast corner of the island and follow the raised path that bears the rebels’ tiger insignia on the right. This pathway leads directly to the camp and the radio tent containing the frequency card and includes a stash of food and an Adventure Book for you.
If you already have the Adventure Book, a quicker method is to dock north of the camp and use your whip to climb over the back wall. This will allow you to sneak behind the radio tent for a stealthy entry and exit.
Wat Mahathat
Wat Mahathat is the large island west of the village and hosts one of the biggest enemy camps in Sukhothai. To reach the camp, dock northwest of Tongdang’s Hut for an easier path to the entrance.
Once you arrive at the camp, crawl through the ruins on the right to avoid detection by guards and dogs. This route will lead you behind the tent where the frequency card is located, but be cautious as multiple guards—and at least one dog—will be nearby.
You’ll find several tools behind the tent, including sledgehammers that you can use as weapons.
After acquiring the card, it’s advisable to exit the same way you came in and return to explore further once you have the Royal Army Uniform.
What to Do with the Radio Frequency Cards in Sukhothai
Once you gather all four frequency cards, meet Gina at any boat dock. You can call her using the dock’s radio if she’s elsewhere.
Once you and Gina are at the same dock, place the cards on the table with the radio. She will give you a draft of an article and mark your map with red X’s. If you visit those marked locations, you’ll find crates containing 125 baht each.
