The Cave

This is the storyline achievement for the scientist, and is unmissable if you take her on the run. Stop reading now if you don't want to be spoilered.

Firstly start off by hacking the Door Control Panel and continue up the hall to a Grog Machine and hack it. After you get to the new hallway, contine onto the water. Swim across and grab the Fuse. Go back over and go up the ladder putting it in the Fuse Box to activate the elevator. Then use it to head on up.

Hack the control panel for the blast door and go back down the elevator. After this head back up again and continue through the door into the laser room. Make it shoot and wait untill it is traveling away from you to run in and hack the console. Take the key and put it in one of the keyholes in the previous room.

Now hack the elevator control button in the laser room and continue downwards, taking the ladder all the way down after this. go left andd take the wet floor sign which causes the floor to become wet. Take this back up to the top off the ladder and go left to the room up another ladder. pt the sign on the button and hack it. After the tech slips, take his key and put it upstairs.

Take the ladder all the way down to the bottom left room to reach the cafeteria and check the speciaal of the day. you'll need to match this to the menu on the notice board (1 floor up and to the right) to get the day of the week, and match this with the random codes from the administrators terminal on the top floor to the right. take this code to the bottom floor and left, imputing it to unlock the door. They'll reset if you do it incorrectly, so don't mess up. Go into the room, grab the Knockout Gas and take it upstairs to the room to the right of the Bulletin Board. Switch characters and go up the ladder past the administrators terminal to find the HVAC control switch. Hit it, switch to the character with the gas and drop it, knocking out the guard, who leaves the third key for the keyholes.

Return to the cafeteria and use the fruit bowl until you get bananas. With these, go to the room past the guard to find a chimp. Feed him a banana and then head to the room down a floor and to the left, making sure the chimp follows. When he enters the rocket, all the requirements to fire are complete. Go back to the keyholes and use them with all three characters. You can now continue down the first evelvator and to the left over the water to continue on.
