Crackdown 2

Best to level up your strength a little before going for this - although if you wait until your up to L5 for strength, you'll probably get this by accident anyway...

Easiest way, once you've levelled up your strength stat, is find a nice area congested with freaks (Unity Heights is normally good for this as it's crawling with freaks at night) Climb up onto a building and jump down into a fairly cramped area of freaks. Hit 'b' at the peak of your jump, and you should come flying down sending those freaks everywhere.... pop goes the chievo!

You can probably do it without levelling up, but it'll definitely be a lot easier if you level up first.

A simple way of nabbing this achievement is to firstly get your strength to level 5 as the damage and area of effect are an adequate standard. Then, start a freak breach mission and when the three groups of three form a midpoint as they run toward you, perform a ground strike (done by jumping and holding B) Obviousley the higher you can jump, the more damage will be dealt. Thats all there is to it. Good Luck!

Fairly easy to get this cheevo. You first need to be level 5 in strength. After that its best to do this at night as the freaks are everywhere. Simple enure at least 5 enemies are around jump up and slam back down. I got this by doing a freak stronghold and just jumped as soon as they started spawning.

This achievement is easy enough, chances are you'll probably end up getting it by accident while playing through the game.

Now, some people say you need to have Lvl 5 Strength to go for this achievement and some people say you don't, the truth of the matter is, you don't. However, going out of your way for it before you're Lvl 5 Strength involves some really awkward methods that don't always work so I recommend you just play through the game and not worry too much about this achievement, if you get it before you reach Lvl 5 Strength, great! If you don't then when you get there just go for the achievement, you'll get it easy enough!

Right, so the best way to get this achievement is to wait until night time, let the freaks come out and claim the city, try and find a group of them and just let them surround you, when you feel they're close enough press "A" to jump into the air and then hold "B" to make your agent perform the Ground Strike move, if you don't get it first time just move down the street a little, let the freaks swarm you and try again!

I've linked in a video, it covers the basics of what to do.

A very easy achievement to obtain. Simply go to a cell tactical stronghold and when your strength is high enough, you'll be able to jump straight down of a huge building into the strong hold around a few guys and pound them all.

If you don't have level 5 strength what I did was land on a car causing it to explode and it kills whoever is by it. I did it by the police station tactical point, the building across the street.
