Circlora: Guardians of Balance — Official Teaser | Cooperative Board Game

About Circlora, from BoardGameGeek:

The forest is stripped bare, and rivers have been polluted. Humans continue to hunt creatures, and ravage the lands. Now they wield weapons powerful enough to bring down dragons. In the forest a wounded dragon appears. Protect the dragon and the forest so they may recover. Circlora is a cooperative tower defense game, where players take on the role of forest spirits to protect a wounded dragon from humans and help it escape. Players take turns to select one of the 3 Action Circles to activate the next action on rondel in order to summon and move the golems. Plan together and move the golems into spaces with humans to defend the area and deal damage. Charge up the dragon's energy, and use your special abilities to hold back the humans. Use the "Dragon Power" action to gradually heal the dragon. If you can raise the Dragon's Power to 12 before the humans reach the dragon, you will be victorious in helping the dragon escape.
