Here's why:
* Cooperative Gameplay: The missions require two players to complete specific tasks simultaneously. For example, one player might need to capture a Pokemon while the other distracts it.
* Two-Player Controls: The game is designed for two players using two separate DS systems. Each player controls a Ranger, and their actions directly impact the outcome of the mission.
However, you can still enjoy the multiplayer missions with a friend if:
* You have another DS system: You'll need a second DS and a copy of the game for another player.
* You have a friend who wants to play: You can connect your DS systems with a wireless connection and team up to conquer the missions.
While playing these missions alone isn't possible, the cooperative gameplay adds a unique and exciting dimension to Pokemon Ranger: Guardian Signs.
