The Outer Worlds

Tactical Time Dilation can be activated by pressing RB.
At level 20 in Ranged, and 40 in Melee, locations will be marked on enemies during TTD.
Hovering over the groin with most weapons will display the "Weaken" status effect.

-As SpinkyDink mentions, the TTD damage zone indicator skill MAY not be necessary.
-Many creatures have groins, robots do not.

In this video guide I will show you how to hit 30 enemies in the groin during tactical time dilation. To use TTD you hit the RB button to start the slow motion. Next hover over an enemy to see the "weaken" effect pop up. Some creatures have these as well, but humans it's much easier on. Once you shoot them you will know you got it by their reaction. They will bend over in pain and stagger a bit.

There are some perks that will make the TTD duration longer and regenerate faster. So keep an eye out for those to make it easier. Also some companions have some similar skills, Parvati in particular has one.

A very important note when going for certain achievements in this game. This achievement might not count if you try it on the same exact enemy. I know for certain killing the same one for weapon achievements will not count. So keep this in mind.

- During the slow-mo "TTD" you need to aim at their crotch and fire away at their nether regions crippling them lol.
​
- Doing this 30 times will net you the cheev bomb
​
- Remember the SAVE trick to help you grind this out faster
One trick that helps with all of the "do this X amount of times" cheevs...use the SAVE feature to RELOAD SAVES helping you grind those out easier. *However people have said that it can cause the tracker to stop going up...so if this happens, try saving after you do one run, SAVE on a new file, then RELOAD the old one. Rinse & Repeat.

This worked for me before installing dlc but on the final update patch on series x.
Set to story difficulty for easiest path to this achievement. (Unless u can't cause you are trying to get difficulty achievements)
Go to edgewater with a automatic weapon.
Find a group of marauders outside the city.
Kill them.
Then just find a dead body and shoot em in the ding dong when in time dilation.
I was able to get the same body on the ground to fill me to 30.
No save abuse needed.

The achievement unlocks after the 30th hit to a humanoid enemy's groin with either a ranged or melee weapon while in tactical time dilation (TTD). You must have unlocked, "Unlocks TTD location hit effect" for the weapon you are using. TTD location hit effect unlocks at level 20 for ranged weapons and level 40 for melee weapons. This allows the weapon used to target the groin.

For a hit to count, enter TTD () and target the enemy's crotch. When the caption, "weaken" appears; you have correctly targeted the groin. Execute the hit by pressing . Each hit to the groin (to the same or different enemy), while TTD is in effect, counts towards the achievement. The achievement pops on the 30th hit.

Note that the TTD location hit effect is unlocked according to the skill level before bonuses are applied. To check, bring up the character screen and tab to the skills page. Highlight the weapon. Base skill unlocks will appear on the right hand side. Each active skill unlock will be highlighted and have a filled-in radio button to its left. For example, if handguns are at level 20 or better, the novice skill effect will be highlighted and the radio button filled in. In contrast, if one-handed melee weapons are below level 40, the competent skill level will be greyed out and the radio button to the left will be empty.

When you target an enemy's crotch, after you have unlocked TTD location hit effect for the weapon you are using, you may see the weaken caption below the targeting reticle or another status effect like maim, stagger, cripple, etc. Some imprecision is permitted but to ensure the groin is precisely targeted look for the weaken caption. The hit may still count if stagger, for example, is shown as the status effect.

To ensure your hits are counting, turn on the console achievement tracker. Designate this achievement as a favorite so you can track its progress. You'll note that you will get credit for many hits in the vicinity of the groin even when the reticle is slightly off. You can even get credit for hits to the side and the back just below waste level. This means an automatic rifle is likely to give you multiple hits even when the aim veers off target. Nevertheless, note that the weaken status effect is the most precise and will guarantee a hit.

If you are in the habit of using TTD, the achievement will pop during normal game play once you have leveled your weapon skills to where location hit effect is unlocked. The fact that some imprecision is allowed increases the likelihood that random hits will strike the groin and count towards the achievement.

The game's system save file keeps track of hits. So every hit to the groin counts even when you reload an earlier save file. If you want to grind the achievement early, an easy location is just north of Edgewater. Enter the town and exit by the NW exit (to the right of the workbench) to bank an auto-save. Conversely, if you are playing on a difficulty other than supernova, you can make a manual save closer to the enemies you intend to target.

For convenience, use the console's tracking feature to monitor progress toward the achievement. There will be 3 marauders just up the road. Approach them until you can target the groin with the weapon you are using. Enter TTD & get as many hits to the groin that you can during the interval. Reload the previous auto-save you made when you exited town (or manual save if applicable). Repeat the process until the achievement pops.
