Wait through the entire opening cinema. Run through the level and photograph the isotope and recover the CamSpy afterwards. Then run for the laser section. No specific strategy is given here as you can do all this at a relatively leisurely pace, and you will still find yourself waiting around for the bot to lead you through the lasers.

 

Wait through the entire opening cinema. Run through the level and photograph the isotope and recover the [[CamSpy]] afterwards. Then run for the laser section. No specific strategy is given here as you can do all this at a relatively leisurely pace, and you will still find yourself waiting around for the bot to lead you through the lasers.

The time at which the bot reaches the first laser is critical. For a good run, you need a good bot, the faster the better. It's as simple as that. However, this time is also - as far as anybody can tell - absolutely random. (It does seem that PD cartridges purchased AFTER the initial release give consistently faster times at the first laser. Make of this what you will.) So there is a significant luck/perseverance factor in getting good times on this level.

It is the section after the lasers where you can actually use your speed to get faster times. As you get to the final laser, go right up to it (hurt yourself on it!) and pause and release the CamSpy on the far side. Use the CamSpy to open the two doors ahead of you and save yourself a second or so. [[Speed strafe]] through and start Data Uplinking the computer next to the locked door, ignoring everybody on the level who shoots you in the back at this point. Carefully turn around and move to face the door while this is happening, but don't let the uplink break. Pause and unpause repeatedly while listening out for the precise time of the uplink completion, then open the door and bolt through.

Strafe like a loon through the rest of the level, avoiding switching strafes for any reason. In the final room with the drone guns, just go straight down the middle and they will not shoot you once. Spam B as you reach the last door.

This is one of the most complex and open-ended levels in the entire game due to its non-linearity. A large variety of increasingly fast and dangerous strategies have been employed over the years.

This is one of the most complex and open-ended levels in the entire game due to its non-linearity. A large variety of increasingly fast and dangerous strategies have been employed over the years.

The general principle of the current world record strategy is to activate the cleaning bot as early as humanly possible, then photograph the isotope, deactivate all three experiments and collect the first two experimental technologies at blistering speed before meeting the bot at the lasers - all while retaining enough energy to survive the suicidal Data Uplink section.

The following explains the ''second-fastest'' strategy for this level and needs altering to reflect the fastest strat. (The main difference is that activating the semi-secret floor hatch is skipped.)

===Activating The Bot===

===Activating The Bot===

Watch the opening cinema until the camera switches to the guard's point of view, and looks up in the top-right corner in the room, then hit A. You should kill the cinema about a second after the guard goes "Huh?" Immediately run forward slightly and then strafe right, shifting the joystick slightly so you bear down on the far door. Hit A before you reach it to switch to Unarmed. Hit B to open the door. If this is your first attempt today, switch to Disarm as you head for the guard here. When you reach the computer, hit Z and B one after the other in quick succession to activate the computer and disarm the guard simultaneously. Left-strafe back the other way immediately.

Given when you quit the cinema, the little brown door that you are aiming for will close at around 0:14.5. So if you get caught on the first door, or miss the computer and have to go back and try again, then you've lost too much time and you'll miss the brown door - pause and quit. However, if you failed to disarm the guard, that's OK. It's hitting the computer that's critical; you can manage with 10 fewer bullets in your gun.

Left-strafe along the long corridor towards the guard who appears around the far corner. Switch to your Falcon 2 as you run, and aim upwards slightly to shoot over his head. Fire one bullet over his head as you pass him and dodge around without reloading. (Sometimes he is further down the corridor - just shoot where his head would have been. It doesn't make much difference.) Switch instantly to right-strafing at the corner and fire the remaining seven bullets madly at the door ahead, the frame around it and maybe one or two in the tiny brown passageway as you switch back to left-strafing and dive left into it. Listen out for the shouts of the alerted guards in the next room, to make sure they heard you shooting. Reload as soon as possible while you round the corner and aim down at the glass ahead of you while still right-strafing towards it. Rapidly fire as many bullets as you like at the glass - it takes four hits to break it - and jump off the edge.

Switch to right-strafing as you fall - not too early, or you'll end up back on the top level again! - and head diagonally for the nearest computer. Reload. Smack the computer and left-strafe away diagonally across the open room towards the second computer. There are two ways to activate it, one about a second faster than the other, but slightly less reliable. The easy way is to simply left-strafe into the corner where the computer meets the wall, hit B while facing the side of the computer, then turn and left-strafe away again around the corner. The hard (but smoother) way is to left-strafe to the computer, switch momentarily to running forwards, hit B as you hit the edge of the computer head-on, then right-strafe for a fraction of a second to avoid actually running into the computer, then switch back to left-strafing. This is all done without stopping moving at full strafing speed for more than a fifth of a second. Try it out, you'll get what I mean, and if you don't, try to figure it out for yourself because it's not too hard. After you've tried both methods, decide which one you want to try to use.

As you arrive at the final door, hammer B repeatedly until it opens and you can check your wondrous time.
