The Darkness II Trophy Guide
One Man Army 
Kill 25 enemies while being dragged from the restaurant, without dying or restarting checkpoint
This trophy is only available on Chapter 1 - "Dinner Out".
If you're playing on Thug difficulty, then this will most likely be the first trophy that you unlock at the start of the game. You'll have to kill 25 enemies while being dragged from the restaurant, without dying or restarting the checkpoint. After shortly entering the restaurant your friend, Vinnie, will lead you to two Italian ladies. A Mob will then blast a hole through the wall behind the two ladies, which severely damage your leg. Vinnie will then try to drag you out of the restaurant and into the alley, while you cover him with the pistol he handed to you.
There are roughly 30 enemies that you can kill, but you won’t be able to kill them all. You only need to kill 25 of them as quickly as possible without dying or restarting the checkpoint. The greatest thing about doing this on Thug difficulty is that the enemies will die in 1-2 shoots. This is fairly easy and I suggest that you kill over 19 enemies while you have the one pistol in hand because Vinnie will eventually hand you another pistol to dual wield. This means that you won’t be as accurate as you were with the one pistol in hand, but will still have enough time to kill the last remaining 6-10 enemies before Vinnie gets you to safety. If you fail you can either press the
button to restart the level or checkpoint, but you can only restart the checkpoint when the twins are killed. Once you gotten the dual wielding pistols you cannot restart the checkpoint.

According to
Phorphuxake the kills for this trophy stacks and carry over with the use of New Game+ only, so if you didn't get the trophy on your first playthrough and decided to jump right into your New Game+ playthrough you'll unlock the trophy naturally. Do note that this doesn't work if you keep replaying the same level over and over again. It has to be from a New Game+ with a decent amount of kills from your first playthrough.
Kills for the trophy carry over with NG+ so info updated.

Tanks Very Much
Achieve level 10 and gain the Tank Role.
To achieve a level 10 and gain the Tank Role abilities you must select either Fire or Ice as your power set from the character creation screen. It is the Tank's role to keep the group safe by attracting enemies' attention meaning it’s your job to reduce the overall damage your group takes. Area effect powers such as pulling enemies towards you and gathering them in one big group will make doing this easier. The best 5 weapon styles for Tanks are the Bow, Staff, Dual Wield, Dual Pistols and Martial Arts. Each style gives a bonus of +30 Defense and +30 Toughness. Once you reach level 10 with any character you created, you will automatically acquire the Tank Role and your trophy will pop.
As of The Battle for Earth DLC based off the ultimate showdown with Brainiac. Earth Powers have been added to the game which are classified as Tank Role.
Roadmap updated later this month. Will be the final update I do towards it as it keeps changing/evolving.
