Two groups with the same objective: BECOME A TEAM, a good team.
You have to talk to each other, understand, debate, compromise, decide and act. The real qualities of a team are those of working together and only in this way will you find achieving a shared objective easier.
With the "paintball hits" you can eliminate the members of the other team or defend yourselves until you achieve your objective: protect your flag, your captain, conquer the land of your adversary or find the treasure.
Protected by overalls, masks, scarves and caps you jump into action committed to both reaching your objective and to your companions.
