Zombi - Solution

  First get Alex to drop the helicopter keys by the helicopter, there's no
  point in carrying them around with you and it will enable you to carry one
  more useful object.

  Choose one of the characters and go down to the security room on the second
  floor, pick up the set of keys and make your way to the list, don't bother
  getting any weapons and don't stop to kill any zombies.

  Use the keys and now you will be able to go up to the fourth floor ( drop
  the keys in the lift, you don't need them anymore ). Leave the lift and you
  will now be in the main control room, and here you will find three different
  keys on the floor, each one of the three will start one of the lorries,
  enabling you to move them.

  Via the lift now make your way back down to first floor and go to each of
  the lorries and using the keys move them in front of the various entrances
  to the shopping centre. The only problem is now that your character will
  not be able to get back inside. Choose another one of characters and send
  them down to the sports shop on the third floor, get the rope, and then go
  to the balcony above the front entrance on level two, use the rope and your
  other character will climb up and onto the balcony away from danger.
  Get one of your characters to get the fuse, the rubber glove and a gun, and
  make another character to get the torch, take them in the lift to the
  basement and get the person with the torch to use it so when you exit the
  lift you'll be able to see where you are.

  Both go round to the fusebox and after you've disposed of any zombies get
  the character with the rubber glove to use it and insert the fuse into the
  fuse box. Now using yet another character go to the forth floor and press
  the buttons on the computer to activate the lights in the basement.
  This is where operation zombi kill starts. Get one of the characters to go
  round each of the levels destroying all zombies he meets and then stick
  all the zombies in the cold store ( if you use the tape from the video shop
  with the TV and video in the rental shop you'll see that you have to shoot
  the zombies in the head to kill them). If you now go down to the main
  entrance you will see that some thugs have moved the lorry and have made
  their way inside.

  Getting the fuel can (level three), a gun (level two), and the hose pipe
  (level one) go outside and go to the right. Soon you will come across a
  van belonging to the thugs, shoot any thugs that are by the van, and then
  drop the fuel can in front of it. Now use the hose pipe and, viola!
  You now have the precious fuel you need to fly away in the helicopter.
  Get everybody inside the helicopter and start it up with key (remember where
  you left it) and the game is completed.
