The account is shared across every demo in the showroom, so items and currency you get in one demo carry over to the others. Loading takes a moment. If the frame is too small, open the demo in a new tab. ## Overview Build parties from the characters you have recruited. Each party has three slots (`slot1` to `slot3`); you start with room for 2 parties and can expand to 4. On the **Party** board you switch between parties and tap character cards to put them in or take them out. ## How to try it 1. Under **Recruit a character**, press **Recruit** next to **Recruit knight** (or another character) a few times to get characters to work with. 1. On the **Party** board, pick the **Party 1** tab and tap a card under **Your characters**; the character goes into the first empty slot and its card reads **In party 1**. 1. Tap the slot card, or the card marked **In party 1**, again to take the character out of the party. 1. Switch to the **Party 2** tab to build another party. The same character can be in more than one party. 1. Press **Expand** to add room for one more party; the caption reads, for example, `3 of 4 parties`. The button is disabled once you reach 4. ## GS2 services used - [GS2-Formation](/microservices/formation/): GS2-Formation's form model defines a party of three slots, each accepting only characters from the `Character` inventory. The player can save 2 parties to start and 4 at most. Slots are filled with signed item sets from GS2-Inventory. - [GS2-Inventory](/microservices/inventory/): GS2-Inventory's `Character` inventory holds the recruited characters; **Your characters** on the board lists it. - [GS2-Exchange](/microservices/exchange/): GS2-Exchange rate models define the buttons: **Recruit** acquires a character and **Expand** adds a party (`Gs2Formation:AddMoldCapacityByUserId`), each run server-side as a free transaction. ## Use it in GS2 Studio In GS2 Studio's Simple mode, open **Add features** and press **Add** on **Party Formation** to bring this feature into your own project.
