Marcus’s Quest 1
After you reach Ancient Sands, you should focus on saving your money before jumping into serious farming. You will need to get at least the Boat Tube and the Crossbow Gun before farming here consistently.
Marcus’s Quest 2
Cod is easy to catch because it spawns often and does not need much power. You can farm it quickly without heavy upgrades. During the fishing minigame, you should grab any treasure chests that appear. After you collect them, you will get extra rewards, including Fish Bones.
Marcus’s Quest 3
The fish needed are still relatively simple to catch in this area. You just need to make sure you have enough Oxygen before heading out. After you upgrade your Oxygen, you can travel farther into the zone and stay longer during each run.
Marcus’s Quest 4
You should continue farming the local fish to keep your progress steady. At the same time, you need to keep saving up money for gear upgrades. After you improve your equipment, you will be able to farm more efficiently.
Marcus’s Quest 5
Grouper usually spawn farther out in Ancient Sands, so you will need to travel deeper into the area to find them. In these spots, Scorpionfish and Sharks can appear and create extra pressure during your runs.
You should carry Oxygen Pods before heading out. After your Oxygen drops low, you can use them to refill and continue farming safely.
Marcus’s Quest 6
You should get the Wasted Gun from Crazy Jeff’s Shop before farming tougher fish in this area. This weapon helps you deal with Scorpionfish and other stronger targets more comfortably. After you equip it, you can handle these fights with better control.
