Co-op gameplay in Double Spiral is a very important aspect and can be considered a core system of the game. Perhaps many people are not particularly familiar with the co-op gameplay in Double Spiral, as the game has not yet been officially released, and only a small number of players have participated in the beta test. It's quite normal for there to be a lack of understanding about this feature. Next, I will provide a detailed guide on the co-op gameplay.

In Double Spiral, the co-op combat mechanism essentially involves summoning companions to fight together. Players unfamiliar with the game might assume that in actual battles, one can only control the main character. In fact, besides this method of controlling the main character, there is also a way to summon allies for co-op combat, which is referred to as the co-op gameplay.

The co-op gameplay allows you to summon AI companions to fight alongside you. This co-op mechanism can be used both in single-player dungeons and during map exploration. When summoning, each player can call upon 2 AI companions to assist in battle.
After understanding the co-op combat mechanism, I'll now share how to set up the co-op gameplay. If players wish to experience co-op gameplay in the game, they first need to set up the characters they want to summon in battle. After entering the game, there is an icon resembling a little person's head at the top right corner of the main interface; this is the game's preparation button.

After opening the preparation button, you'll find an option for the tactical backpack, which is the last button among many. Opening the tactical backpack lets you see the characters you currently own. Equip your desired summonable characters with melee and ranged weapons. Don't forget to equip the magic wedge for your weapons, as it significantly boosts their combat power.
Once the weapons are equipped, drag the characters into the wheel. It's recommended to prepare several summonable characters. After completing this step, you can enter the dungeon and start battling. During the fight, simply press the T key to summon your companions.
