This issue brings you a gameplay guide for the Double Helix game. The game, with its dual main storyline and the novel setting of freely switchable weapons, has attracted many newcomers. However, beginners may encounter various issues that affect their overall experience. To help everyone get started quickly and embark on this exciting adventure, the following guide will help you understand the basic gameplay.

Ⅰ. Character Recommendations
The game features numerous characters, each with varying levels of strength. Currently, the more powerful characters recommended for acquisition are Saki and Truffle & Hazelnut. Saki is a strong damage dealer, with unparalleled strength in both single and group battles. It is suggested to unlock and cultivate her until the second passive skill is unlocked. Truffle & Hazelnut can deal considerable area damage through charges and also provide healing for themselves and nearby teammates, along with an effect that increases damage.

Ⅱ. Dual Weapon System
The dual weapon system allows players to equip two primary weapons for their character, one for melee and one for ranged combat. Each weapon is categorized into blue, purple, and gold qualities, with higher quality weapons having better attributes. Weapons of purple quality or above come with special effects. For example, the Radiant Blade's weapon skill has a 25% chance to restore 5 points of Sanity when the player scores a critical hit. This Sanity acts as the player's mana bar, essential for casting skills to attack enemies. In practical play, it is advised to use the ranged weapon for long-distance harassment, then switch to the melee weapon once the enemy gets close for hand-to-hand combat.

Ⅲ. Weapon Cultivation
Besides the basic level-up and breakthrough, the weapon cultivation system also includes the addition of Demonic Wedges. These can be understood as items embedded in the weapon to boost its attributes. A total of 9 wedges can be installed per weapon. However, pay attention to the tolerance value, which represents the amount of tolerance occupied by each wedge. Once the limit is reached, no further wedges can be added. Upgrading a wedge will increase the tolerance it occupies, so it’s important to manage this value carefully during the upgrade process to avoid situations where the weapon cannot be used after upgrading.
Ⅳ. Collaborative Partners
In addition to switching between two weapons at any time during combat, players can also summon assist characters. Summoning an assist is simple: just place the character in your quick-access bar if you own them. Since the assist character is controlled by the system, it is advisable to choose support types with wide-ranging effects. For example, Fina can summon a field that deals continuous damage to enemies within and provides beneficial effects to teammates, making us stronger.

Ⅴ. Dungeon Content
Each dungeon has its unique gameplay, different difficulty levels, and reward materials. For instance, in the Exploration and Defense dungeons, the objective in Exploration is to quickly clear out surrounding small monsters, helping to obtain blocks, and then using these blocks to speed up the progress of the explorer. Once the progress bar is full, we win and receive copper coins. In Defense, you follow and protect the explorer, helping to clear three waves of monsters, completing which rewards you with Demonic Wedges and character skill materials. Regardless of the type of dungeon, each challenge consumes stamina, which can be managed based on the materials needed.
Ⅵ. World Exploration
During exploration, you will encounter various small monsters and challenge missions, which are relatively easy. Defeating them or completing tasks can help you gain generous rewards. Additionally, you might encounter Spirits, which are similar to pets. They have their own abilities; for example, "Purple Mist Black Cloud" can deal dark attribute damage to nearby enemies and provide a boost to allies, increasing our output. This is like having an extra skill, so consider capturing them when encountered.
