These achievements can also be completed in the first playthrough.
As for the tips, I can say this:

• Do not get into a direct fight.
  
• Collect nanocatalysts from the corpses of Cephas to upgrade your nanosuit.
  
• Shoot at the uncovered parts of the cephs' bodies for effective destruction, especially the Bomber.

Close Encounters
Stealth kill 25 enemies

The best way to complete the achievement is to kill the Soldiers of the Sell Company, as the animation of killing them is faster than the cephas.

Death Grip
Kill 10 enemies with grab and throw

Death Slide
Kill 5 enemies while sliding

Headhunter
Kill 4 enemies in a row with headshots

The best way to complete the achievement is to kill Sell soldiers, as the animation of killing them is faster than the Cephas. You can complete it by finding a pistol with a silencer in the mission "Sudden impact" at the entrance to the car park after the cutscene with the destruction of the Cephs' ship. Shoot only in cloaking mode as the shot consumes 10% of energy and enemies will not see you.

Band of Brothers
Keep all marines alive during the rescue in Semper Fi or Die

It is very easy to do after Chayno has found you, run ahead of the marines and kill as many cephas as possible. If you fail, just lower the difficulty of the game. Personally, I got this achievement on Warrior of the Future.

Blast Radius
Kill at least 3 enemies with a single grenade

Also, a very easy task in the mission "Second chance" you will be taught how to throw grenades, so take one and hold it until a notification about the possible loss of a limb is displayed and throw it at the 3 soldiers in front of you, as in the video.

Stealth Assassin
Re-route the power in Eye of the Storm without being detected

Originally posted by Rarity💜:

In this task, in the episode "Eye of the storm", Colonel Barkley drops you to capture Hargreave, so you need to go through the entire segment completely on stealth without killing ANYONE! The achievement will only count after the substation is switched off, after which you don't have to hide). If you still fail and someone notices you, Hargreave will say: "That didn't take long. I think you need to be more careful."

Hole in One
Throw an alien down the sinkhole in Dark Heart

In the episode "Dark heart" you will need to intervene in the last cephalic spore distributor and then evacuate. Right next to it is the mine channel.

Originally posted by Rarity💜:

Keep in mind that there is a Bombardier (a large, full ceph) in this sector, so I advise you to take any ceph (except the tank and commander) by the throat better than the one that is directly looking at the mine channel and throw it.

Popcorn
Kill 20 enemies with the Microwave cannon

Originally posted by Rarity💜:

In the episode "Dark heart", when Hargreave asks you to detonate the explosives of Reeves' men, you will find this weapon among their corpses and shoot the spiders running around if you are not going to use this weapon. Keep in mind that it only does a lot of damage at close range and only against lightly and medium-armoured cephs. If you don't have enough spiders or ammo, don't worry, I will mark all the locations of this weapon during the game.

Two Heads Are Better Than One
Kill two enemies with a single bullet

Originally posted by Rarity💜:

The achievement is easy and difficult at the same time because the artificial intelligence of the CELL fighters is very stupid, so they can often stand in front of each other and you can fulfil the conditions at any time. If you, like me, accidentally did not get this seemingly easy achievement, I will show you an easy way to do it.

Originally posted by Rarity💜:

You need to shoot from the right corner of the pier fence (you need to stand on the leaves) where the yellow containers are located. Calculate the location of the reticle and shoot, if one CELL operator is standing, restart the checkpoint, if not, you will get the achievement).

Food for thought
Kill a CELL operator with a giant donut in Lower Manhattan

Originally posted by Rarity💜:

On the roof where you get the grenades on the left there will be a large donut that falls from a shot or a blow, you need to calculate that the CELL operator is under it. You need to wait and not disturb the enemies because they will never approach him. You may not succeed on the first try and that's okay because the game counts this achievement very strangely. I personally, as you can see in the video, sat on a semi-trailer and shot a donut with a pistol with a silencer from this place, and you can shoot from whatever you want, the main thing is that it falls on the enemy's head. If you don't understand something, I will leave the guy's video of how he did it.

Here you will find all the information on the locations of souvenirs and motion sensors. I advise you to look for them after completing the main campaign by replaying specific episodes on the lowest difficulty level. If you are not satisfied with my table, I will leave the video.https://www.youtube.com/watch?v=RHRWDh9Smac
