PUBG: BATTLEGROUNDS (UP)

50 grenade kills. Potentially the most troublesome achievement of the lot if you want a fast completion.

Firstly, for those unaware of how to use the grenades:
press to pull out your grenades. Press it again to cycle between Concussion, Smoke, Molotov and Frag grenades should you be carrying multiple types of grenades.
hold to show the grenade trajectory assist (note, this is made by the developers to be inaccurate at ranges, so don't count on it if aiming at a small window from say 20 metres away.
Optionally, when you tap you will start cooking the grenade, starting its five second fuse before it will blow up.
Tapping will switch between throwing underhand or regularly. Be cautious when trying to underhand a grenade say, off a balcony, as it will more often than not land at your feet even though the aim-line showed that you'd be safe.
Letting go of at any point after pulling out the grenade will cause you to throw the grenade, unless you haven't cocked the pin by pressing ; and only by pressing Y to cancel the grenade before letting go of

So, a couple things to start off:
- Knockdowns with grenades and them bleeding out does not count. Neither by killing their team or waiting for bleedout timer.
- Finishing your teammates' knockdown with a frag grenade does NOT count.
- As for most of the [kill x amount of players with x weapon or equipment] achievements, you can down an enemy by any means, so long as you finish the player off with whatever you're trying to progress the achievement of

What does count:
- Any kill in a solo game (Sanhok is unreliable, I recommend not playing that map until it is fixed if you're only after achievements).
- Finishing a knockdown of your own with a grenade. (The knockdown could be with anything, but finishing has to be with a grenade.)
Edit: the refer to the comments bellow for the comment made above this line. Apparently finishing with a grenade after knocking with a gun does not work anymore.
EDIT: Tip from Acurate Bob on my Crossbow solution, although I haven’t tested this, he reported if your teammate crossbows an enemy you downed, you get crossbow kill progress; if this works I would assume the same thing works for grenade kills.

There's a few ways you can go about doing this:
- Play squads with some cooperative friends.
- Play solo squads so you can knock down an enemy and finish him with a grenade
- Play actual solo

The latter might be harder for some as they can obviously shoot back if they're not knocked down, however it was how I went about doing it.
try to always have grenades on you, and ALWAYS prioritize grenade kills even if you're trying to work on other achievements as well; Something I didn't do and cost me some time.

Now you can go as hard on this as you want of course; Personally I played the "Anything for a grenade kill" way, dying a few times with no kills as a result.

If you don't care about fast completions, a squad of friends will be the easiest yet not fastest way of doing it.

Depending on your skill level as a player, and your strategic preference, only you can be the judge on whether or not you want to hot-drop to find people quickly, or want to sneak up on people late-game.

Both guides above are great, but if you aren't good in the game like me to get this easily I got a method (it's not mine but I'm just sharing it).

First you turn off the cross platform option in the menu and change to FPP and solo squad, now just wait a few minutes and you will be probably in a match filled with bots. From now on it should be a piece of cake, get some guns and after finding the grenades start killing the bots and when they're down finish them with the grenades, also be careful because they can end up running away from the grenade if you don't cook it enough.

here is a video guide on how to do it with a boosting partner.
basics of how to boost
1. same servers and same cross platform settings
2. search at the same time and check code under the map to be sure you are in same map
3. choose landing spot and find grenades
4. have partner pull pin on grenade with right trigger and throw your grenade at his feet and after they explode run to there body to explode from there grenade



THANKS @JOLLY548 FOR HELP ON THE VIDEO
below that is a guide to do it on afk
to do this with afk people ride the plane to the end and see gow man are there and land on buildings as close as possible. if you find a grenade run back and throw it at there feet and hopefully kill more than one
