SUPER ANIMAL ROYALE

This achievement is normally really hard and long because of the bad grenade controls, but you can of course easily get this one too! Just go to the Most Populated Server at the time, I joined EU. Then wait until the eagle kicks you off along with the other AFK players, land before them, and get a grenade or two from the local buildings/campsites. One grenade will kill someone with no armor if it's thrown right on top of them, one skunk grenade will kill someone with no armor if thrown right on top of them. I got around 2-3 kills per match.

If there aren't any AFK players or too many players at the end then quit the match quickly and join again to be in another server.

This one will be the hardest/longest achievement of the game, because the aim system for grenades is awful with the controller.
You will use RB/LB to select grenades in your bottom right bar and you will throw them with RT, and you have to aim with your right joystick to adjust the distance.

My advice is to go on squad mode, and spawn in the Super Pyramid. You will find grenades and get some weapons to fight quickly. Your objective is to down ennemies with your grenades, and finish them off with any weapons you want.

If you down an ennemie with another weapon and finish him with a grenade, it doesn't count.

People on squad mode tend to stay in groups, so here's your chance. Another solution is to down an ennemie and wait for his friends to come try to revive him: when they're packed, launch your grenades and hope for a down before finishing the job.

Another tip by MiggyBombs: you can wait and drop at the very end with some AFK players, find some grenades near them and kill them that way!

Good luck!

Grenades are weapons found around the map.
Use RB/LB to select them in your bottom right bar and then you can throw them with RT

Achievement Walkthrough:

This achievement is frustratingly difficult. It will take as long as getting every other achievement in the game combined. I don't like developers that put these kind of random, difficult and rare circumstance achievements in.

That being said I do have some advice on how to get this one. Play solos in a less populated server and have fill on. This will load the game with bots. Their A.I. is set to rush you if they damage you and you are weak. So land by but away from a player you think is a bot. Find a grenade (way too rare) and then find a bot and shoot them a couple times. When you are yellow or red health, keep diving away while they chase you and line up the throw so they run into it while trying to hunt you down. Do this a painstaking 10 times and you will have this awful achievement.

This achievement is actually super simple and can be done in less than an hour with the right gamemode.

In S.A.W vs Rebellion (a Game type that switches out with the bwoking dead) there are multiple points where your enemies will be trying to capture a flag, before you spawn in select the ‘heavy’ player type and this will give you one regular grenade which can do a lot of damage.

Take this to one of the flag points where a generous amount of players will be and make an accurate throw towards them there’s a high probability you’ll get a kill and with ‘heavy II’ you’ll have two of these grenades in your inventory.
(May take some luck but otherwise actually pretty easy)

I just wanted to add if you are playing duo or squads you have to knock them down with the grenade then you can kill them with gun (you have to kill them not your team mates or enemy players)
I mainly went in to Europe squad crossplay on as people mostly stick together but it is possible you can do it in crossplays off but you have to wait longer for games
