This is it, the last mission in beating the game. You will need all eight badges to enter the Pokemon League. Go to Viridian City and cut west, to the place where you first caught Nidorans and your second battle with Gary. Go west from there and you will see a big building. Go inside. Show the guards your badges and you will be allowed to go through. You will have to go through a lot of rooms, each one with a guard asking for one badge. You will eventually come to a large room with fierce wild pokemon and trainers, as well as boulders like in Seafoam Islands. This time, you will need to push the boulders onto switches that open pathways that are blocked by rocks. The descriptions are below each map.

Push the boulder east, onto the switch located in the middle of the east wall screen. This will open the pathway north of the switch that was blocked by rocks. Get the items and go to the ladder at the north west corner, marked A. Push the boulder near the steps onto the switch located at the south west corner. This will oepn another pathway. Take the first ladder you see. THIS PART NOT FULLY COMPLETE! GO TO ELITE FOUR WALKTHROUGH FOR NOW! Click here to go to Elite Four Walkthrough!
