Out of the Box: Firesiege - A Feralis story

About Firesiege: A Feralis Story, from BoardGameGeek:

Firesiege. A feralis story is a limited-information cooperative game. Each player controls a Valkun Hero with unique abilities and skills, and turn after turn you play action cards to resist the siege of the army of Skreel that are crawling into the city of Medda to kill your leader Norad. The enemy army is nearly infinite, thus to win, your troops must outmaneuver the Skreel by fulfilling different goal cards (E.g., sealing the three Nests of the Skreel, rescuing inhabitants of the citadel of Medda, recruiting enough Marall mercenaries to overcome the enemy, and so on) till they have managed to flip all 6 Banner tokens on the Victory side. Each game will present players with a different challenge depending on the Goal cards selected! Be aware though, that each action in battle triggers a reaction: i.e., when playing a card, you get to know only one side of it - while all the other players know the other side but not the one you know. Communication is crucial to success, but of course, in battle, you are not entirely free to speak out loud about your plans... Both sides of the card you play must be resolved, and one is always good (light side) while the other will affect you negatively (shadow side). If your Hero dies in battle, an enemy sneaks into the city center, or the Incubation track reaches its maximum, the game is immediately lost… Choose wisely which and when effects should be played, as all actions have consequences and any card could be the last one! -description from the publisher
