2/2 - In the green room where the two waves of enemies attack you (one of the spots for Vigilante) The game will tell you "Go left or right". You want to take the path that leads to the left (if you just came up the ladder, it will be on your left. Walk to that gate so Nite Owl will open it.

The easiest method to do this one is with Nite Owl. I played through the game to gather abilities first. Once you have the abilities, you can use your Electric Nite Owl Charge to keep yourself safe throughout.

I did the first level and just spammed R1 and Square during fights to continuously counter attack. When I would come upon large groups, before going to those spots I would let my charge ability fill up so that I could shock them all right away then beat them down quickly.

You can actually just mash both R1 and Square at the same time, you don't have to bother with timing. The only trouble spot to watch out for is the room that is on fire as the fire can and will hurt you. Be especially careful.

Another method is to do it during a co-op game: Make sure you are controller 1 as nothing that controller 2 does will aid your stats or reward you trophies. You just let your partner fight off all the enemies and stay back and safe. You can also do this method in the single player game and let your AI partner do all the attacks. Again just stay back.

You are supposed to complete the game in under 80 minutes for this trophy, however...

I'm not sure if the timer is glitched (in your favor) or if maybe the cut scenes and finishing move cine-matics don't count in your time, because timing myself (with a stop watch), mine came to 85:19 when I defeated Underboss.

I did it with Nite Owl after I had all the abilities. I utilized the electric shock anytime there were BIG enemies around as they take the most time to defeat. I found that by throwing enemies (with circle) you were able to defeat them faster, because it only takes three hits with them on the ground and you can knock down groups of them by throwing one guy into the middle of the pack. If you are high up, throw enemies over rails or into water to save time. When you are separate paths, you often don't have to kill all enemies, just avoid them and move to the next section. However, if it is a section where you will be opening a door or grappling, you will usually have to kill them before you can move on.

On Underboss, DON'T worry about any of the enemies while you are chasing him. Until you battle him for the first time, the enemies won't really bother you if you just keep running. The first enemies you must kill are the big posse just after Underboss goes up a ladder, there are a bunch of them. Hopefully you've let your "charge" fill up because one burst with that and they all die and you can move on. Once you start battling him, you do have to clear all enemies before going up the ladder.

There are two places that I found to do this.
1) In chapter 4, just after the big battle in the water, Rorschach will climb up a pole to open a big door for you. You will then go down a tunnel and then turn right into a very green room. Go up the ladder, and a big battle ensues. There are two waves of about 12 guys each. Just button mash and take them all out as fast as possible. I did it in about a minute. And don't worry about your team AI killing enemies. Don't do this with a co-op partner because their kills won't aid you, they will hinder you and you will come up short.

2) During the final boss battle - when you are at the top of the building and he is standing above flame throwing, stay in one of the sides where the endless enemies comes and just take out 20 before finishing him.

This one will be easiest to do in the first two levels as the enemies are easier to pick up and toss. After level 2, the enemies block a whole lot more. The tosses accumulate across all your play throughs, so don't worry about getting them all in one play through.

To do counter attacks, you press R1 then Square when you are engaged with enemies. The easiest method I found is to use Nite Owl and just spam R1 and Square as he seems to counter attack almost every time. Counter Attacks accumulate across you plays with either character.

To do Finishing Moves, simply press the button indicated above an enemies head. Repeat 249 more times. These are mostly done on the bigger enemies found in the chapters. Some times, you will get lucky and while doing a counter attack it will slip into a finishing move too. Finishing Moves accumulate.

This should be the first trophy you get. To dodge, play as Rorschach and press R1 when you are in battle. To block, play as Nite Owl and hold R1 when enemies attack. You only have to do 25 with either character, or 25 total between both. You should get this fairly early in chapter 1 if you try.
