Webswinging is a lot faster than in the PS2 game. Sometimes it can be so fast that its easy to lose momentum, and wind up walking through the street, or crawling on the side of a building. I've unlocked the ability to hit X twice in order to gain speed, and that has made it a lot easier to stay in the air. When finding backpacks, crimes, or other things on rooftops, I find myself drastically overshooting the landing zone. I wish there was a braking ability or something. I haven't unlocked all the webswinging abilities though, so it may be there down the line. Also, it may just come down to how skilled I am with the game.
The game gives you ways to earn extra XP such as stealthing three enemies, but I 'm having trouble figuring out how to get the list to appear during combat.
You can use web shots (default R1 gadget) to lure enemies to specific spots. Hold L2, aim with analog at the spot you want to lure then press R1. Enemies close enough will get a question mark above their head and will walk to spot.
Clicking R3 will do a scan of enemies in area. When looking at one close enough, you'll see a *danger or *safe by them. If they have *safe by them then you can stealthily attack them without alerting anyone. The square attack will web them to you and hide body in web if used from a wall or perch. The triangle attack will just launch you to their location and knock them out silently but it will leave a findable body there.
You can use L2 then R2 to move to a perch (when white circle appears at spot) or the ceiling or wall (when reticle turns green).
Stealth is fairly easy once you learn all that.
