Don't kill any EuroCorp civilians with the minigun in chapter 8
On chapter 8, a ton of EuroCorp civilians will be running shortly after you kill a reactive armor and jack his minigun. A bunch will run out in the beginning, which are easy to avoid, but as you make your way up, some more will poor out from a door on the right. Take it slow, and if all else fails: melee everyone. You don't have to use the minigun, and enemies can kill civilians without negating your attempt.

Use the Swarm's multi-target lock-on firing mode to kill 3 UAV drones with one volley
Obtainable shortly after picking up the SWARM for the first time. Drones will be pouring out of the contraptions soon after picking it up for the first time. Breach the shields of three of them, and then lock on to each one. Fire, and destroy them all in on volley to get the achievement. If you mess up, it's okay; the drones endlessly spawn until you shut off the machines.
Kill 3 specters in chapter 14 without using EMP effects on them, on normal or hard difficulty
Spectres are the cloaked guys. There will be a few of them in the level near a bunch of EMP mines. Watch for their movements and fire at them without breaching any of the mines, or using EMP grenades. There's plenty of chances to get this, as there's 10 or so spectres.
Make it past the conveyor belt without taking any damage from the turret
The conveyer belt level is on Chapter 15 of the single player campaign. As soon as the level starts and you exit the vent, do not move. To your right is the turret that you have to avoid. Kill the enemy directly in front of you and peek out just enough to see the conveyer belt controls that you have to override. Overriding the conveyer belt moves along a box that you must keep between yourself and the turret as cover. You have to go up the room once, then back down (killing the enemies along the way) with the box as cover, utilizing the conveyer belt controls to keep it moving along the way. When you reach the second room, you can shut off the turrent, and when you finally exit that area, the achievement should pop.

Kill Agent Crane before you kill his two sidekicks, on normal or hard difficulty
This is on Chapter 18 of the single player campaign. You'll be notified with a cutscene after you drop down from a vent when you hit the boss fight, so you'll know for sure when you're on it. To stay alive, simply use the pillars (raising them with a breach when necessary) and dodge around the lackeys - don't use persuade or anything on them, as they may kill each other, or time may run out and the persuaded lackey may commit suicide. The achievement will pop when you down Agent Crane and extract his chip.

Kill enemy soldiers of two different syndicates fast enough to receive a rampage energy bonus
This is pretty simple. Just load up Chapter 19 and find any area where there are black soldiers and white soldiers fighting one another. All you have to do is kill them one after another quickly enough for your rampage bonus to go off. You can do this right after you hit your first outside area after opening the door-like thing... just shoot one guy on the platform, then one guy down below under cover.

Unlock the Datacore in the minimum number of breaches
At the end of Chapter 19, you'll encounter a big round door with lights surrounding it. Simply overlay (and you have to use overlay) and breach one side, then the other. If you miss it somehow and fail, just reload your last checkpoint to try again.

Obtain a health bonus from network connection links from your upgrade choices (single player only)
This is achieved by linking two upgrades that are side by side on the agent chip upgrade menu (accessed by hitting the back button on your controller). It doesn't matter what two upgrades you pick so long as they connect to one another.
With Friends Like These - 15
Kill an enemy from the explosion of a reactive armor unit
The first time you can get this achievement is on Chapter 8 and best played on easy (just so you don't have to worry about the lackeys). You'll know you're at this point when you encounter a cutscene with a big, white armored guy holding a minigun. Breach the big guy's armor and shoot his health down, then do the same thing again. When you have breached him twice and shot down his health, lure him over to a lackey and breach him one final time. His explosion should take out his friend, and you will get the achievement immediately. If for some reason you fail, you can also reload your checkpoint and start right at the beginning of the fight.
