This minigame was made for players who wish to socialize with other players. Most of the weapons in the game cannot be used in this minigame. There are exclusive gear items such as Cupid's wings or bear costumes.
There's also a weapon exclusive to this map called "Just A Hand", which is actually the player's hand. When you choose it in the melee section, your character is shown without wielding any weapon. Also, it is the only sandbox-exclusive weapon shown in the Armory.
So far, Chat Stickers can be used in Sandbox and in the competitive chat.
