Heres how to do it fast and easy :
when u reach the top of the wire , jump left and cross under the wire after wich you jump to the right to find the first spot where u must enter a battery , this will activate the propeller . Jump up and across the wire , Then jump left to get to the train tracks , where u will find the 2nd battery spot . This will activate the gate , giving u a way across .Cross the gate , climb up the wire and then u must jump to a swinging rope , watch a few times while u count from when its coming to u untill it squeeks , jump right before it squeeks and u should have it , else retry this . Scale the pipe to the next area and climb to the wire to the left . Climb down there to reach the last battery box , where u get an ether from . Then just do the jumping again , go to the next screen like before , climb up and across the wire , scale the pipe and ur at the shinra HQ !
U can choose whether u sneak in (climb MANY MANY stairs) or bust in , i suggest busting in , cause its fun and is like free experience :)
Just battle ur way to the elevator , wich will go berserk when ur in it , it will stop at random numbers giving u random enemy�s , wich are sometimes stronger then the others u have faced , but they cant be a to big problem . Soon u reach the higher levels of the building .
Now u reach the higher levels of the HQ , this part can be quite the challenge , but if u stick to this guide ull be just fine ;)
(59th) : Aproach the guards that await at the right elevator , defeat them to get the pass u need to reach the 60th level . Enter the elevator and go to the 60th level .
(60th) : Easy , head tothe left upper room and ur party will split up , walk to the statues and stop when the guards try tosee you , when they start walking go on to the next statue . When u make it to the first half u must signal the others to pass the statue�s in the same way . Do it again for the other half . If u get caught dont worry ... u will just have a small easy battle and begin in the left chamber again , if u fight the battles ennuf times the guards will eventualy dissapear anyways :D then simply walk up to the 61th floor by using the stairs in the right upper chamber .
(62th) : A tricky one , if u cant get the secret code in 1 turn u wont get the extra present , well anyways , here�s what to do : Go to the left of the floor where u find the mayors office , talk to the mayor inside and he will promise u the card to the next floor if u can guess the code . Go outside and u can talk to the deputy mayor for a hint , ill help ya out so u wont have to waste money on him . Go to every section of the library , in every one is 1 book that doesnt belong in it , put the letter that belong with the book together and it should spell the pasword (or you save before the mayor and just guess a few times , reloading after each wrong awnser , thatll work aswell) If you do it correctly you will get the 65th card aswell as an elemental materia (if you add it in your weapon linked with an element it adds that to your attack , in armor it will help quard against that element .).
Exit the room and circle the parameter of the floor counterclockwise untill a door on the far side blocks your path , open it and proceed to the left door on the near side of the next section of hallway . Open it and enter the room on the left to find the A-coupon. Climb into the air shaft (secret) and climb to the right middle room and pick up the B-coupon . Exit , proceed to the door in the near left corner of the next section of hallway , and open it . Enter the next room to find the C-coupon (the last one) . Return to the computer trough the ductwork and redeem the coupons for : a star pendent (give to cloud !) , a four slots (armour) , All materia (cant have ennuf of these !) . Now just walk the stairs to the next floor
