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.

Finally, while it is not recommended, you can skip most fights by following the instructions detailed in the Fifth Floor section.

Items

 * Ultra Ball (Hidden in the bottom plant of the southwest office)

Third Floor
If you need combat experience, don't hesitate to seek out every Team Rocket agent and challenge them to duel.

However, if you want a quick end to this situation, follow the instructions from Fifth Floor so you can grab the Card Key, which will open every electronic door in the building. Then come to the Third 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.

Read the info in Seventh Floor for information on the challenges and rewards that await you on that Floor and beyond!

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 take warp tile G, then come back though the same warp tile, and follow the path to the right and you'll find the Card Key. With that you can open any of the locked doors! Check the info in Floor 3 to make your way up to the top!

Be wary of the bald guy on this floor, for he's the one of the only ones to use Psychic-types Kadabra and Mr. Mime. If there's a Pokémon on your front line with low HP, it'll be quickly knocked out, 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 Blue. Before stepping out of pad O, make sure to bring a wide variety of Pokémon types to exploit his party's weaknesses and ensure that your Pokémon are at least level 35 or above.

After defeating your rival, go back and heal at either the Pokémon Center, or on the beds located in the Ninth Floor. You only have tougher fights ahead.

Also, this is where you can receive a level 25 from the person standing at the other side of the room. Lapras can be an excellent addition to your team, especially if you did not choose Squirtle as your starter, as it is a very powerful Water/Ice Pokémon. Step on pad P and head to the Eleventh Floor and your next challenge!

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 the Ninth Floor, where the girl by the beds will heal you.

Giovanni is tough, but easily beatable if you make use of type advantages. 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 Pokémon that is weak against Water, Ground, Psychic, and Ice.

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, but this is the only one you'll get in the entire game, so be sure to save it for a special occasion (such as the Legendary beasts). When you're finished, you can collect the items in the now Rocket-free lower floors.

Finishing up Saffron City
Now that Team Rocket's plans have been thwarted, all the buildings that were blocked by grunts are now accessible such as the Gym and the mimic girl's house. Head back to the Gym to face Sabrina
