3 - Skyrails. This system of winding, undulating rails connects certain parts of Columbia. How you'll use them does not help explain how they work. You can "hook" on to them and be propelled around the skies of Columbia with a free ability to shoot or land on any balcony, terrace or other major flat surface as you do. You can even hit a button to pull an automatic "U-turn" in the opposite direction while staying on the same rail. Now how this makes sense according to the laws of physics is beyond us. But you should already be over that by the time you get to these. The game is set in a freaking floating city.
