Display Cases
Microchip: 3
Microchip 1
The first microchip is very easy to get. Walk right. Along the way you will encounter two spiders hanging from above and one on the floor. Nothing to worry about. There are also Missiles to collect. When you reach a wall, climb up, kill the spider and jump to the left, to climb onto the display cases you just passed under. At this point proceed left, going around the display cases to collect all the DNA strands. There are no enemies here. On the last display case you will find the microchip.
Microchip 2
Once you reach the wall on the right, instead of jumping on the display cases, continue climbing and you will come to a curved ventilation shaft. You can jump from side to side to get the DNA strands above, but be careful not to fall onto the fan, or you will die. There is also a Smart Bomb at the top. Kill the spider and exit into the next room. Here you have to proceed by holding on to screens and small ledges with exposed electrical cables underneath. Don't touch them, or you will hurt yourself. However, there is only one path to follow, you have to reach another ventilation duct at the top right. Be careful of the spiders, which patrol some of the screens, and do not fall into the void. There is a health capsule under a screen, in the bottom right. Go through the duct in the same way (there is also another health capsule) and reach the next area. Now you have to proceed past small gaps and avoid getting hit by swinging steel balls. If you get hit, you will immediately lose a life. Timing is key. Immediately after the third swinging steel ball, there is a short platform with a health capsule above and the microchip below.
Microchip 3
Follow the entire path described above to reach microchip 2. This time continue, passing another swinging steel ball and follow the path, jumping over the fans. There is a health capsule after the first vent. After passing some very narrow platforms (be careful not to fall), you will come to a vertical wall. Reach the left side, going around it and climb to the top. Continue right and, after defeating a last spider, you will arrive at the last microchip.

Microchips: 3
Microchip 1
Go left, jumping from rock to rock, avoiding the intermittent flames and being careful not to fall into the lava or you will immediately lose a life. Be careful though, on the second rock from the start you’ll encounter a dangerous scorpion, a tough enemy that can also shoot you, like wasps. Better if you have some powerful weapons. Another one in waiting for you two rocks ahead. Shortly after, you will encounter a wasp. Climb the rock wall taking the DNA strands, turn the corner, take the Poisoner and go down. You will have to overcome another stretch similar to the first. There are no scorpions here, but on the other hand you will find many wasps and a spider. There is a health capsule to recover energy on a platform. You will then arrive at a very high rock pillar. Climb to the top and jump to the right, where you'll notice a row of DNA strands. If you do everything correctly, you will get a CD piece. Be careful though to fall directly under it, or you will end up in the lava and lose a life. Go back to the top of the stone pillar and turn the corner. You can now choose between a higher and lower path. Take the upper one and carefully advance onto the suspended platforms, without falling. On the first there is a spider. You will find another spider a little further on, on a small platform. Kill it and drop into the gap between that platform and the next one. Fall straight and you will end up directly on a microchip suspended in the air. Really well hidden.
Microchip 2
Reach the stone pillar described above. This time, if you want to change, you can take the lower route, which is perhaps a little easier. In any case, the two paths rejoin later. On the lower path you will have to jump from platform to platform eliminating some wasps. There are very useful Missiles along the way. Then climb the vertical wall on the left (along the climb there is also a health capsule) to reach the point where the paths rejoin. You'll probably notice a shield at the base of this stone wall, on the other side, but you can ignore it because it's basically useless. Stay at the top and continue left, jumping from one suspended platform to another, being careful not to fall and eliminating the wasps. At the end you will find the microchip.
Microchip 3
Another very well hidden microchip. Follow all the steps described to get the previous microchip. This time, however, instead of entering the green exit bubble, go under the platform on which the microchip was previously located and let yourself fall. You will land directly on the last microchip.
