Gears Of War Ultimate Edition - Insane - Act II: Nightfall

Tick Tick Boom almost instantly starts with a split path decision.
Left allows you to lob a couple of grenades from behind cover and get a Boomshot, but right feels better defended overall.
After a few minutes you'll regroup near a Troika and shortly after Grist Begins almost seemlessly.
The 13th COG Tag is right at the start of Grist so it would make sense to have the time stamp for it first. Head outside and take out the Boomer (preferably with Grenades) and then slowly advance to the right. I do grab this Boomshot and keep it alonside the Gnasher, but almost immediately after swap back to the Lancer I generally prefer to play with the Gnasher and a long ranged weapon for most of the game, but in Act 2 Grenades are fine for your weapon to take out heavier targets.
Once you head down the stairs head backwards down the alley for the 14th COG Tag.
In the more open road segment get behind and quickly push a car all the way to the end and take out the Troika with a Grenade and mop up before finding the 15th COG Tag near the end of the Chapter, just left of the settlement entrance.
Advance through the settlement for a cutscene and the next Chapter of 1 minute of walking.
I die right at the start of Lethal Dusk, but keep it in rather than edit it out.
Outside shoot the propane tank to light up the area and then grab the Longshot. I keep the Lancer for here, because there's a few long range targets that I would rather just use a shot of the Lancer for (the propane tanks mainly). There's also no opportunities for enemies to get closer for the most part because the Kryll will rip them to shreds, as is demonstrated with the light going off by some humans. Look for Propane tanks to advance by the cars and at the end of the alley on the left you'll find a Propane Tank that will allow you to nab COG Tag 16.
Down the right you'll see a Troika and some enemies near it. A perfect opportunity to use the Longshot before shooting more Propane Tanks to get there. At the end of here on the left you'll find a house to go into, and immediately get ambushed by a Wretch. Chop it up.
Then you'll come to an outdoor area with an E-Hole. I got a lucky Grenade in it and then advanced to the left, I headshot the Locust with the Shotgun before it could advance and end up at a car you can push to adcance. IT's easier to get to the side of the Troika and lob a Grenade in the room and then destroy the Propane Tank from above.
Outside in a courtyard area there's a lot more enemies, and shutting the E-Hole would have helped, but a couple of Longshot shots save the day.
You'll come to a Spotlight to mount that you use to guide Dom to the end of the street. At this point aim the light near the Crimson Omen and head down to nab COG Tag 17. Advance down the next alley and head into the building with smashed windows to get shots off on the Locust behind cover. They'll struggle to advance because of the Kryll. further along you'll find a drunk human who plays with the lights as a prank, Dark Labyrinth begins here.
Slowly advance through the building as the drunk guy lights up the way for you and you'll find COG Tag 18 outside on your right.
On the left you'll find a car with a Propane Tank. Shoot it and Roadie Run alongside to reach the Petrol Station and end this short Chapter.
Outside turn the wheel until you come off it and then head back into the building to deal with Locust. Despite it being a petrol station, shooting the Propane Tank to lower the car to the left is viable. A couple of Wretches and a Boomer appear. Luckily the car was blocking the Boomer so a couple of Headshot took it out with no retaliation. Then more Locust advance from the right so I deal with them, the chapter ends shortly after this wave and now you have a driving Chapter.
In Burnt Rubber you'll have to drive and shoot along the way. The human with you will help spot for you, so just know your clock positions and you'll know where to aim. I do pretty poorly (mainly one segment near the end which took off around a third being the culprit) as I end up with around 40% health, but knowing in advance from the footage where the Kryll comes from makes this even easier.
Last Stand is a chapter mainly about positioning, looking towards points of interest will help you decide where to hide at any point. The group of Boomers from the E-Hole can be Headshotted or Grenaded and they can't move far. The chapter and Act ends afterwards and Dom drives us all off in the Junker
