Grand Mountain Adventure: Wonderlands takes the player to a ski resort. The game is an arcade skiing simulator with a top-down view. The gamer is given 12 vast resort areas to explore with high mountains, slopes, forests, cliffs and small towns. Locations are open for exploration and filled with hidden collectibles, and you can quickly move between areas using lifts. In addition to skiing, in Grand Mountain Adventure, you can get on a snowboard. In addition to game characters, NPCs also ride around the area, cars and trains drive, and animals roam in places remote from populated areas. When sliding down steep peaks, the gamer should be careful, as an avalanche may come down from the mountain. The gameplay is given variety by the presence of all sorts of modes and challenges.Among the many disciplines in the game are:
- Super G or super giant slalom - a high-speed descent from a mountain with the need to drive through gates made of flags.
- Slopestyle - acrobatic jumps from ramps and slides.
- Big air - snowboarding jumps from huge ramps with the performance of various tricks in flight.
The game also has a local multiplayer for up to 4 players. Users will be able to get together with friends, compete or explore the snowy expanses together, throwing snowballs at each other. In contrast, there is a Zen mode, in which the player can relax and just ride without restrictions, for their own pleasure, in complete unity with nature.
