The Amazing Spider-Man 2

To acquire this achievement you need to preform fifteen combat takedowns, this is when you stick the enemy to the floor or wall with webbing. You will be required to have your "Web-Shoot" fully upgraded, this will grant you the "Stickiness" upgrade.

However it will require the targeted enemy to be very close to a wall, the best option for this is starting a "Petty Crime". Any one which has them breaking into a buildings door, you can just web them straight away with B.

Others are a little trickier trying to herd them close to walls, so my advice upgrading your other skills as these will help.

I found the easiest way to do this is to fully upgrade "Web Rush" and "Web-Pull". This will unlock "Stun" and "Clothesline", this combo of skills gives you a great advantage.

When in a fight use "Clothesline" attack using RB and then furiously tab X, this will then send the enemy flying to the floor stunned. Once on the floor, run up to him and the tab B. You will find him webbed up and out of the fight, just rinse and repeat.

Remember that when ever an enemy is stunned then just hit B, the rest will just fall into place over the course of the game.

Good Luck
