Complete the game as Rorschach in single player. You cannot get this achievement in co-op.

Complete game as Nite Owl in single player. You cannot get this achievement in co-op.

Complete the game in co-op. This has to be done locally with a second controller because there isn't online co-op.

Requires you to pick up all abilities and Rorschach cards as Rorschach. At the abilities screen it tells you how many Rorschach cards out of ten you have collected and which abilities you have. Use THIS guide to find the abilities or cards that you're missing, and THIS guide for video locations of the cards.

Requires you to pick up all abilities and Owl Suit batteries as Nite Owl. At the abilities screen it tells you how many Owl Suit batteries out of ten you have collected and which abilities you have. Use THIS guide to find the abilities/batteries you're missing, and THIS guide for video locations of the batteries.

The best way to get this is to have a friend use the second controller on the first chapter in co-op and have them do all the fighting while you run away from the enemies. When you get to one of the rooms with the two levers, stay in that room and have your friend clear the path to the next room with the last two levers. Move up and stay in that room and have your friend finish the chapter. If your friend dies or if you lose health, including touching flames even slightly or taking a hit, just select restart chapter and try again.

If you don't have a friend to do it with, you can get the AI to fight them for you. On the first chapter, run up and get the enemies to run at you, run away and get them near the AI. Once the AI is fighting them, run far away. If one of them chases you keep running, and loop around back to your AI and run away from him again. If you're fast enough, the enemy will stop and turn around to fight your AI partner.

Play as Nite Owl because his charged owlsuit ability will help greatly. If you charge the suit in a group, any small enemy can be killed with 1-2 strong hits afterward, if it is not killed by the charge itself. Try to have a charge ready for each fight and it'll be over quickly. Collecting all the batteries first will help with this. Uncharged, his ---- combo will kill enemies in the first two levels in one combo.

Try to run through and when you can't progress without killing the enemies (some ladders, some doors, etc.), kill them. If there's a "pit" nearby (over the railing in the prison, off rooftops etc.), throw the enemies off for a quick kill, if you can't pick them up, use the knock down/fast knock down ability when the enemie has his back to the "pit". You can also stomp them 3 times and the third stomp will be an instant kill on any enemy. You can only stomp them when they're down. Just play through as quickly as possible. If you die, exit to the main menu and start over, as the achievement states "without restarting from a checkpoint".

Save the electrify owlsuit for Nite Owl until there's a very large group. Some suggestions are the large sewer area with the pillars, the sewer area where the enemies drop from the catwalk, and the fight at the end of Chapter II before entering Rumrunner. When you get to the fight, run in the middle, (Fire charge), then beat them up as fast as you can. Other people had luck with it in the last level with Underboss, right at the end instead of throwing people at Underboss keep killing them, throwing them off the building is quicker.

As Rorschach, when you see an enemy winding up to attack you, and in a direction away from the enemy and you'll roll. As Nite Owl just and you'll block. Do it 25 times and you'll have the achievement.

When you get the throw move, will throw enemies. I find the prison level the easiest as you can pick almost all of them up without weakening them. Just and in the direction of the enemy you want to pick up, then flick the towards another enemy. The enemy has to fall down for it to count. Repeat 100 times.

As Rorschach, when you see an enemy winding up press and in the direction of the enemy to spin behind them, then + when prompted, the game gives you about 2 seconds. As Nite Owl, hold and when prompted +. When in Rage Mode as Rorschach, he auto counters when someone goes to attack him and you press . Do 200 and the achievement is yours.

Focus on finisher moves, where a certain button (either , , , or ) pops up above enemies heads after you've beaten them up a bit, press the button, short animation. Do 250.
