About Union City Alliance, from BoardGameGeek:
A Cooperative Superhero Deck and Board Building game for a team of 2-4 Players. Each chooses an iconic champion to play as and work together to confront and defeat a central supervillain. Each hero has their own unique starter deck of Origin cards that highlight that character's unique strengths and skills. Each Hero also comes with a Deck of super-powerful Solo Cards that only they have access to, featuring their most powerful abilities.
On their turn, players will explore to add new map panels to the board. Each Map Panel contains new Union Cards to add to their deck. There are also City cards with Challenges to overcome and Enemies to defeat, collecting outrageous rewards. Beyond that, Map Panels have Actions and special set-ups so you never know what's going to be around the corner! Players control how the board is built and a one-of-a-kind Map is constructed each game.
All the while, the Peril of the Supervillain grows, their plot escalates, and they unleash minions, maniacal machinations, and bring their own formidable combat prowess to bear. Each Supervillain has their own means of conquering the city, each time you build the board it is different, and each Hero has their own powers that they can add to and hone as part of your own Union City Alliance!
