| You get an achievement!
This level has one or more achievements. The achievements are listed on the level infobox.
Level 17 is the seventeenth level of Run 3.
There are many holes in the tunnel, and using the Skater can let you skate on the holes with ease. His incredible momentum can let him skate on the holes easily, and you will be able to navigate along the level. Just look out for the large patches of crumbling tiles, since there are a lot of them.
There is an achievement that can be done by finishing the level. More can be seen in this page.
Keep It Simple Edit
In this achievement, you need to dislodge every single tile in the level. This shouldn't be too hard, since if you use the Runner, her slower speed can let you maneuver easily and is slow enough to walk right into another pile of crumbling tiles. As the patches of crumbling tiles are stick together, you just need to dislodge one of them. You just need to dislodge 4 crumbling tiles, since there are just four batches of crumbling tiles.
P.S. You need to finish the level after dislodging all the tiles, or it won't count.
Its reward is 50 power cells.
