An old colleague reach me to help him on his project.
The game Destiny was just out and he saw a lack of group making UI when starting a raid mission. Raids are know to be long & intensive missions. The matchmaking of your teammates was based on aleatory. Players have to get online to create groups manually on web forums. It was not very good gaming experience so we decided to make a project to solve this lack of feature from Destiny 1 game.
