Pokémon Red and Blue/Silph Company

'It turns out that Silph Co. is being forced to produce advanced technology for Team Rocket. You must reach the top floor and free the company president from Giovanni's clutches. If you roust Giovanni, you won't have to defeat the rest of Team Rocket's agents individually. When you need to heal your Pokémon, look for a woman at the bottom-left corner of the ninth floor.' This 11 level building, with 31 trainer battles, only seems difficult. If you know where to go, you can make it to the top and save the President quickly and easily. Then, after scaring Team Rocket away, you can get the items with opposition.

The first floor lobby is eerily empty, so just advance to the stairs in the back. Note that the guard blocking the entrance to the building won't stand aside to let you in until you've cleared Pokémon Tower.

Note that the red circles on this map indicate the warp points that connect two teleportation tiles with the same letter to one another.
