You will get Hijack ability in the beginning of Act 3 - Part 1. To get achievement, you need to hijack 4 types of enemies, and while they hijacked by Jack, they must kill someone. You can complete this one in Act 4, or in Act 3. Here is the list for Act 3.

Stump - Act 3 - Part 1, in the beginning (when you get part from Baird).
Elite Hunter - Act 3 - Part 2 in Rocket Facility, room with one hunter and few locusts with shotguns.
Warden - Act 3 - Part 2 in Rocket Facility (when you need to unlock the door), a little bit tricky but possible (in insane it's possible too). Leave Elite hunter alive and use control on warden.
Pouncer - Act 3 - Part 2 in Rocket Facility, first platform with satellites, two pouncers.

You need to retrieve 5 heavy weapons via Jack's Fetch ability ("Fetch Heavy" - must be opened up in Core upgrades). Easiest way to do it - collect all of them in Act 2.

Tri-shot - Act 2 - Part 1 (first fight after generator)
RL-4 Salvo - Act 2 - Part 1 (near Silverback)
Mulcher - Act 2 - Part 2 (Train tunnel)
Buzzkill - Act 2 - Part 4 ("Nethercutt" Mine)
Cryo Cannon - Act 2 - Part 5 (Laboratory, before fighting boss)

Start a game of Horde on beginner as Jack with bots, or a friend, and build a forge as quick as you can. You can build it right away if you start at a higher wave in the horde options. I usually start on Wave 18 or 28 to get some of the scion weapons. Here's the list of weapons you need to convert.

Boomshot - Dropped by Scions
Breaker Mace - Dropped by Warden
Buzzkill - Dropped by Scions
Claw Light Machine Gun - Dropped by Elite Drones
Cryo Cannon - Dropped by Scions
Dropshot - Dropped by Scions
Embar - Dropped by Snipers, or it can be purchased by Fahz
Enforcer - Dropped by drones, or anyone playing Del
Gnasher Shotgun - Dropped by enemies, or anyone playing Marcus, JD, or Kait
Hammerburst - Dropped by enemies
Lancer with chainsaw - Dropped by anyone playing Marcus
Lancer with Grenade Launcher - Dropped by anyone playing J.D
Retro Lancer - Dropped by anyone playing Kait or purchased by Marcus
Longshot - Dropped by Snipers or anyone playing Fahz
Markza MK1 - Dropped by enemies or anyone playing Fahz
Mulcher - Dropped by Scions
Overkill - Can be dropped by enemies, a teammate playing Del, or purchased by Kait
RL-4 Salvo - Dropped by DR-1's
Torque Bow - Dropped by Hunter Elites
Tri shot - Dropped by Stumps, Guardians, and DR-1's

Your main goal is to destroy everything that's in the Hive with a gas bomb. The bomb contains venom poison so what you don't kill, the poison will kill for you. But keep in mind that the gas will not only kill the Hive but also you and your team. If you are too slow the gas will catch up to you. The bomb explodes in 60 seconds so you have a minute to get as far away as you can and then keep avoiding the gas.

When you escape the pod, the enemies won't be aware of this. You can kill many enemies in one minute but try to perform as many stealth kills as possible before the gas bomb explodes and everyone is aware of your presence.

The main reason behind this is to preserve ammo which is a big deal in Gears 5 Escape mode. Ammo management is key to success here so avoid using ammo to kill enemies before the bomb explodes. Make sure to mark enemies before a melee kills as it lets you deal more damage.

Escape mode is a great way to get comfortable with weapons you don't usually play with. Your favorite weapon will be out of ammo most of the time but you can pick up weapons from downed enemies. You can also share weapons with your teammates, just drop it for your teammate to pick up.

There are ammo areas around the map so do some exploration, the gas takes some time to reach you. These packs only give you ballistic ammo so don't expect grenades etc. If you can't find ammo, keep switching weapons by picking up enemy weapons.

In Escape mode, you can carry one sidearm, one primary, and one secondary weapon. We suggest keeping at least one shotgun with you. The map isn't huge and there tight spaces and area, a shotgun to the head can deal significant damage. Shotguns are also a good way to damage the Flock and Leaches. You can use Overkill to deal significant damage to both these enemy types.

When a Flock charges jump out of the way to avoid damage. Keep a track of its location to avoid being surprised by its attacks.

During the later part of the match, you will come across enemies that explode when they die, they are called Poppers and are new to the Gears universe. Do not melee kill these enemies and keep your distance. They love to explode near you.

Leave one enemy alive so that you can pick up all the drops easily instead of having to race against the clock. Get familiar with all the weapons as you can run out of ammo so don't be reluctant to grab any gun you can find and start shooting.

Keep Longshot or Markza around to kills larger enemies which require some focused fire.

Do everything possible to save yourselves from sires. These nasty creatures will drag you away from your team for good which means you cannot be revived.

Scream, shout and beg for help from your teammates to help you out if one of them catches you because if they don't before the timer runs out. You'll be dead.

In Act I: Shot In The Dark, after separating into two groups and going to the right, you will enter a sewer. At the starting area of the sewer (before going through the archway), shoot the four valves (two on the left side and two on right side) until they start smoking to spawn the Fish Stick weapon. This weapon runs out of ammo quickly. Once it runs out of ammo, your character will drop it. It can only be used again by reloading the chapter and activating the Easter Egg again.
