Gears 5

You can complete nearly all Jack's achievements @ Act IV Ch 1.
At this point you should have alot of component points left to get
Barrier (Take all 3 abilitys)
STIM (Just Revive; cost 8)
Cloak (Speed + Duration)
Hijack (Duration)
Shock trap (Nothing needed)
Flash (Range)

Load it up, get to the point where the swarmak is, and rush to the warden
-> Use Barrier and reflect bullets of some drones - you should leave at least one

-> let ur Teammate get downed by the warden and use STIM for revive
-> Hijack him and let the warden get a kill, thats why u should leave a drone
(1/4)

Proceed further to the Rejects
->Use Cloak , and get the 3 kills for

->Reload checkpoint . rush in, take right path until you come to this room and use Shock Trap to hit 6 enemies


->Reload, repeat and use Flash instead - hit atleast 3, you can do it earlier too.

->Reload if you want to get 100 Reject Execute - takes about ~15 min


In the next Room you can Hijack the Stump and get a kill with it (2/4 Enemy Among Us)

Proceed, you will open a door an see the next enemy you are going to Hijack. Wait till the Pouncer jumped down and Hijack him and get a kill (3/4 Enemy Among Us)

Clear the Area, then you need to defend the area. In the first wave the last enemy for the achievement appears, the Elite Hunter (invisible/cloaked Torque Bow Drones). Hijack one , let him kill a drone and you are done. (4/4 Enemy Among Us)

Unlock Jack's Stim Ability and buy the "Revive" upgrade

- Once unlocked press near a downed friendly to revive his using the ability
(Will unlock for BOTH players if playing in Co-op)

- I started Act 4 Ch 1 w/ 2 controllers. Me on Beginner and the other on Experienced (Insane won't let you get DBNO, you just die)

- Then just walk the 2nd player to the car cover, make sure to buy the "Revive" upgrade, then press once he/she is downed before your friendlies pick him/her up

You will get the Stim Upgrade in the middle of Act 1 to walk through fire.

Upgrade Stim 3 Times

When your Partner is down walk over to him and press Y --- NOT X!!!

Note: Of course Jack must have equipped the Stim Ability!!!

Didn't feel like waiting for an opportunity to present itself, so I gave it a little nudge:

Make sure you have the appropriate stim ability unlocked (10 points cost iirc)
Any difficulty below insane (insane has no DBNO)
Act 3 chapter 2 in the silo at least one encounter has exlpoding barrels strewn about. Stand near one to draw over a teammate or 2, shoot it when they're near, hit Y to cast revive. Done.
