This achievement can get a bit irritating without the proper loadout.
Setup: Player Match
> 3 vs 3 Akrid Survival
> Research Lab
You only need 2 people to start the match. It's an 11 minute match, divided into three 3 phases. First two phases you fight Wardeyes. In the last phase, you verse the other team over control of a Credit
capture point. Which means, you'll only have about 6 minutes to get your 20 kills. Just before the end of the second phase, she'll tell you, "...you're half way there, don't stop now."
This is your 30sec warning before all the Wardeyes leave. Don't be fooled, they can take a lot damage and will kill you quickly.Recommended Loadout
Primary :: Assault Rifle w/ Incendiary round upgrade
Secondary :: any weapon you prefer
Grenade :: Disc
Deployable 1 :: Ammo
Deployable 2 :: any
Ability 1 :: Grenadier Pack (adds +1 to your grenade inventory)
Ability 2 :: any
You should be able to get over 20 kills with this.
The Incendiary rounds hit a bit harder. You only get 40. Hold '
' to switch to them. The Disc grenades will finish them off easily and you'll have 3 of them. If you need to replenish, either pickup an ammo pack or drop a deployable. The depoyables use T-Eng, so as you kill the Wardeyes, be sure to pickup the T-Eng they drop.
All of the upgrades (Incendiary Rounds, Ammo Deployable, Disc Grenade & Grenadier Pack)
are unlocked through the progression sphere.
That's about it.
