1. Rules read that small figures may move from 1 tunnel token to an empty token matching the same color for 1 movement point. Are the two tunnel tokens considered adjacent?

2. If a rebel figure parks on one of the tunnel tokens does it effectively render the tunnel useless for the Imperial player? - since he is now unable to move a figure to an empty token of the same color.

3. Can players make ranged or melee attacks through the two colored tokens?

Don't have that mission in front of me. That's from the R2-D2 & C-3PO pack, right?

That said:

1) It is dependent on what that specific mission states. There are other missions where tokens are used in this fashion to represent tunnels, and it is specifically stated in that mission (Return to Echo Base) that the wall between the two spaces do not block adjacency, counting spaces or movement.

2) No. Movement cannot be blocked in this fashion. The Imperial player may have to spend extra MP to move through, but it does not "block" the movement.

3) See #1.

1. The mission rule does not say that they are adjacent, so they are not. There is a wall between the mission tokens.

2. If you park a figure on the other end of the tunnel, yes. (It is no longer empty.)

3. No, they are not adjacent nor have line of sight. (There is a wall between the tokens.)

2. If you park a figure on the other end of the tunnel, yes. (It is no longer empty.)

Probably should not ask this because I am not looking at the mission, but this situation would still be treated like normal movement, so if the figure still had available movement points and did not end its movement, then what is stopping it from continuing to move? is there some mission rule that is preventing it?

A small figure can spend 1 mp while on a tunnel to place his figure on an empty space containing a tunnel of the same color."
