HAWKED

Pretty straight forward you must deal damage with each type of grenade. There are 4 currently.

Frag
Poison
Anti shield
Stun

Just deal damage with each one and achievement is yours !
Doesn’t have to be done in a single game
I found the anti shield and stun to be quite difficult to find in squads and upon loading a solo game I found them almost instantly.
The grenades can drop from chests or crates
Also this must be done to RIVAL OPPONENTS not the monsters that go around the map

If they add more grenades in the future I will update the solution

Enjoy !

For this achievement you'll need to inflict damage with all grenade types.

Grenade types are:

Frag (You'll always spawn with this)
Poison
Anti shield
Stun

To make this achievement easier you'll want to use the 'Flare gun', Which can be found in the loadout, under 'Ward'.
This ability lets you call in a care package which drops various things such as Health, armour & grenades.

While in a match you can use the flare gun to get all the grenade types. After spamming it a few times, you should get the ones you need.

Now all you need to do in inflict damage onto rival renegades, you can do this in multiple matches so don't worry if you don't get them all in one match.
If you want bots in your match I would recommend using dead servers such as 'Oceania' or 'Asia'. Match que time might take up to 10 minutes but you'll be guaranteed to get more bots then real players.

I've made a video for example where I use all four grenades on one renegade:


Hope this is helpful.
