Boundless Stride Into the Denlands Board Game Explained

About Boundless Stride: Into the Denlands, from BoardGameGeek:

The Denlands are under siege! Floods, fires, rockfalls… no creature is safe. It’s up to you, the newly-appointed Scouts, to protect your home and neighbors from disaster. You must get to the bottom of the catastrophes by exploring treacherous terrain, investigating strange structures, and driving off the mysterious GREM creatures who are growing in number (and mischief!) In Boundless Stride: Into the Denlands, you’ll assemble a team of 4 Scouts out of 6 playable critters. Lead your team to explore the land and complete scout missions. As the story unfolds, permanently unlock new locations, maps, and missions in this unique, co-operative legacy game. The game itself evolves over the course of multiple plays, with map stickers, location modifiers, new abilities, and hidden codes. The innovative open movement mechanism in Boundless Stride creates a feeling of exploring the wilderness. Each scout uses a unique set of track tokens and a special ability to move across the map in a freeform way. The game includes four colorful maps that are completely free of grids or pre-defined movement spaces. Instead, you’ll use track tokens to construct a path for your character, carefully matching each track token with the terrain beneath it. On the way to objectives, you’ll reveal encounters that may grant resources, offer special actions, or trigger new content from the encounter book. In Boundless Stride: Into the Denlands, the rules and components of the game will permanently change through repeated plays as you place stickers, solve puzzles, mark progress, and record your findings. As Scouts, you'll explore the vast Denlands, charting the stars, learning new animal languages, and uncovering the mysteries of the GREMs. —description from the publisher
