How to unlock the Pounding the Pavement achievement in Saints Row IV - Definitive Guide
Sometimes kills will count as shatter kills instead of stomp kills. If that happens you can just ground pound. Provided it is upgraded enough it should kill enemies by itself.
This is an ideal spot to grind just about any power or weapon kill up to this point. For this particular achievement, just stand near where they spawn, let them do so, stomp, repeat. This is by far the most efficient method I was able to find.
A word of warning: as of when I did it at release, the game doesn't like to count Stomp kills very often no matter where you do them. So, just keep at it. It'll unlock sooner or later (as you can see, I do indeed have it).
An easy place to grind is within a Hard difficulty Super Powered Fightclub activity, there is one in the centre of the map (Shown in the video) start the activity and complete the first wave.
Now you'll start the second wave which is King Of The Hill, ignore the hill and instead stand on an open flat area. Several men with bats will continuously come for you and agro to you now which is perfect as these still count as aliens. Make sure you have the Stomp super power selected with and then press to stomp the ground, hopefully they will die from the impact/colliding with a wall as they are low level aliens. (You may need to jump before Stomping else them hitting you will interrupt your attack)
You have plenty of time on the counter to get all 150 but if you happen to fail make sure you EXIT the activity to start over else your kills will not count for your challenges
Here's a video
I found this to be much easier during a certain side mission. It is one of pierce's side quest: back to the basics. (It is his first side quest, not the loyalty mission) This quest requires you to initialize a virus injection where you will have to kill 101 prof. Genki mascots. Just keep jumping (so you can earn kills towards 'I am become death') and pressing RB until you've killed all of the mascots. I know this will not get you the achievement but you will be a lot closer to it than when you started :)
The easiest one to kill with I found was the rock/earth stomp once you've upgraded it, as the gravity one doesn't do much damage and just makes everyone float and so you have to shoot them. Switch using until you get the right one.
If you've finished the game and need aliens to spawn, walk into a shop and shoot the shopkeeper for instant reputation.
The Stomp Super Power is the third attack you gain, which is selected with . As the name suggests, this stomps the ground either from on the ground or in midair using , damaging the Aliens around it. However, this is rarely lethal on undamaged Aliens, so you'll either need to Stomp more than once, which can be a pain, or damage the enemies first. Finish off 150 aliens using this to get the trophy.
A very good way to grind this is to load up a virus upload activity that has Genkis instead of Aliens. The best one is in one of Pierce's side quests, you need to kill 101 enemies. These enemies will die in one hit from any super power, so you can get close to the allocated amount of kills then leave the area so it resets the activity. Once the timer hits zero, run back and start the activity again. Another method if you've done this is the hard fight club. The second wave is a king of the hill, just stay out of the area and kill the weak enemies that will flock to you. If you have Enter the Dominatrix, you can also grind kills on the second mission of it. You'll be attacked frequently two cars at a time.
