Being a point to point movement game, you can only move your team members one tile away. Research members are incapable of moving diagonally. When moving out of the Base or a Personal Hub, one can move two members at a time. Once out on the field, if you choose to move them, they can each move 1 tile away.
Above you see how the game goes after a certain amount of time. You can also see, for example with yellow, that even though they have found a Double resource, they do not have a member on it so they do not receive those points. you can also see how the Radiation tile was just placed by Grey and in Blues next turn, he must move his men out of the blast zone or build a hazmat suit.
