Art Fight:

Art Fight is an annual art game that lasts for 1 month. Users can register on the site to join in. Each year, participants are split into two teams to which they are assigned randomly.

Players "attack" people of the opposing team by making art of original characters you choose belonging to members of the other team. You are free to use most any style (see Attack Rules section of Rules). Your team receives points based on what you create for the other team with each attack.

The artist that receives the attack can then counter that attack by drawing the character belonging to the person who attacked them, or pay it forward by attacking a different person on the other team.

At the end of the month, the team with the greater score wins.
