Pokémon FireRed and LeafGreen/Silph Co.

'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.'

First 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 without opposition. You will need the card to open the door for a warping panel that leads to the Rocket boss. While the warping panels are annoying, the items are well worth it!

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. Also, Silph Co. is one of the very few buildings that you can use your running shoes in.

Third Floor
If you need combat experience, don't hesitate to seek out every Team Rocket agent and challenge him or her to duel. If you want a quick end to this situation, however, run straight up the stairs to the fifth floor and grab the Card Key, which will open every electronic door in the building. Then come to the 3rd floor, and use warp tile O to reach the 7th floor, then step on warp tile P to reach the hallway outside of the president's office.

Fifth Floor
Don't be confused by all the teleporters: The elevator will take you to any floor you want, and you only need to use one series of teleporters to get to the right part of Floor 11.

First go to Floor 9 take warp tile G to floor 5 and get item A, the Card Key. With that you can open any of the locked doors. Then head down to level 3, unlock the door in front of the teleporter marked O, and then take that to the 7th floor, where Gary awaits.

Be wary of the bald guy on this floor--he's the only one to use Psychic-types Kadabra and Mr. Mime. If there's a Pokémon on your front line with low HP, it'll be knocked out pretty quick, so be sure to put a strong Pokémon on top before entering battle.

Seventh Floor
Even if you can best the Rocket members and Scientists here, you'll still be in for a tough fight with your rival. Bring a wide variety of Pokémon types to exploit his party's weaknesses and ensure that your Pokemon are at least level 40 or above.

After defeating your rival, go back and heal at a Pokemon Center. You only have tougher fights ahead.

Ninth Floor
By the time you reach the 9th floor, your team is bound to be a bit worse for the wear. Visit the woman in the lower-left corner of the floor to fully recover your Pokémon's HP and PP.

Eleventh Floor
The teleporter right past Gary (P) takes you directly to the 11th floor, where players will have to deal with two more Rockets before approaching their boss.

Boss
Then there's Giovanni, the leader of Rocket. After you busted up his racket in Celadon City, Giovanni moved his base to Saffron City. It's too bad for him you arrived in time to short-circuit his new scheme. Defeat Giovanni's, , , and to rescue the Silph Co. president.

He's not any tougher than Gary, but you'll definitely need to be in peak condition to stand a chance. Before engaging Giovanni, use Dig to warp back to the Pokémon Center, or retrace your steps and take the elevator up to floor 9, where the girl will heal you.

Giovanni is tough; impossible if your Pokemon are not at higher levels than his. Nidorino is weak to ground, so dig will make quick work of him here. Rhyhorn is a ground/rock type, so metal claw or water moves work well here. Use a high power attack on Kangaskhan that KOs it in one or two hits. Nidoqueen is a poison/ground Pokemon that is weak against water, ground, physic, and ice.

After deafeating Giovanni, if you need to use, use the PC in the corner. Store and then withdraw a Pokemon to completely heal it. Head back the way you came to the room your battled your rival in and talk to the worker. He'll give you a level 25 Lapras, a water/ice Pokemon that's one of the strongest in the game.

When you've sent Giovanni running, the president of Silph Co. will be ecstatic that you interrupted his "meeting" with Giovanni. To reward you for breaking Team Rocket's hold on his company, he'll hook you up with the incredible Master Ball. This technological wonder will catch any Pokémon without fail, so be sure to save it for a special occasion (such as ). When you're finished, you can collect the items in the now Rocket-free lower floors.

All Roads Lead to Fuchsia City
The next destination is Fuchsia City, where you can finally get HM 03 (Surf) and HM 04 (Strength), the last items needed on your quest. There are two major routes you can take: Routes #12 through #15, which is south of Lavender, and Routes #16 through #18, west of Celadon City. The latter path is quicker (and you can pick up HM 02, Fly, on the way!), so it is covered first. But you'll need to take Route #12 to get the Super Rod at some point.
