The Spider's shadow achievement in Spider-Man: Shattered Dimensions

My suggestion for this achievement is to stick with it. The most frustrating part is to get to the first check point. My recommendations are to be patient and to go slowly through it. The first three guys should be taken out with no problems before the first cut scene where the train worker comes out. I dropped down and took the guy out on the ground before taking out the guy who is guarding the train worker.

Then the train worker opens the door. You can sneak to the right of the train and take out the first guy with Hammerhead there with no problems. Then give a few seconds for Hammerhead and company to get through the doors and climb on the right wall and then take down the guy on the right. Then walk around to the left and take out the next guy before rescuing the second train worker.

Now comes the hard (and frustrating part). This took me several dozen times to get but hopefully the system will work. Let Hammerhead and company talk it up and let them go through the doors. Then go all the way to the left of the screen and first take out the guy nearest the exit to the level. Once he is taken out there are two guys guarding the final train worker. What I recommend to do is take the guy on the left out first. How I did this was to climb on the wall and then do a takedown on the left guy from there. Once he is dead, then fall to the ground and do a take down on the final guy before rescuing the third train worker. There is one more bad guy in the next room before you get to the first check point but be patient and sneak up on him and he will be easy pickings compared to the rest.

I didn't have any difficulties with the rest of the level. I recommend to stay in the shadows and take people down one at a time. In the final train yard where there are five hostages to rescue, I recommend taking down all the bad guys first before rescuing the hostages to prevent you from being accidentally spotted.

Best of luck! This is a frustrating achievement that takes a lot of patience, but was actually rewarding when I accomplished it! As a reminder, if you are spotted, go to "Quit Level" to take you to your previous save point.
