The Cyber World of the Delta Rune is actually the 2nd chapter in the game, and there are many hidden bosses in this chapter. So how exactly do you unlock them? Today, I will share with you a detailed guide. When players first enter the game, they will encounter a salesman. Let's see how to unlock [the bosses]. The method is quite simple.

Players need to meet Spenton first, and then proceed on a non-violent path, mainly relying on trading to win. After arriving at the save point at the entrance to the Queen's mansion, players should immediately return to the garbage area and walk left to find the shop ahead. Of course, the next steps after seeing the shop are also important, directly affecting whether or not the player can unlock the hidden boss. Upon entering the shop, the player needs to choose to buy a key. It's recommended to pick the first one, something cheap. All the items he sells are fake, so there's no need to select high-priced items, which would be wasteful.

After purchasing the item, the player can start from the entrance of the mansion, continue walking to the right, and eventually come across a room filled with statues of the Queen. If you helped the hacker on the Cyber Plain earlier, he will now repay the favor by giving you a hint. However, even without his hint, it's fine; the player just needs to activate the hidden switch to continue forward. There will be a path leading to a basement. The subsequent operations are not particularly complex; the player just needs to follow the steps.

The puzzle in the basement is actually very simple, but there will be a spinning cup at the front that poses some difficulty, so be cautious. Finally, the player gets a disk that can be taken back to the shop and given to Spenton. At this point, the player also needs to accept the conditions, then return to the basement again. After returning to the basement, place the disk inside. Once the player puts the disk in and walks out, the boss battle will begin. After completing the fight, the player can talk to the butler at the shop's entrance, and a new message will appear. Returning to the garbage area, the player will encounter several people; talking with them will reveal Spenton's story. Finally, return to the castle. Talking to the old cat will unlock the hidden boss.

How to unlock the hidden BOSS in the Cyber World of the Delta Rune? Players can unlock them through the steps mentioned above. Unlocking is relatively easy, with no overly complicated parts. However, players still need to pay attention to some details during the operation, and if they can master the techniques, it will be smoother.
