Easy "Anyone See That?" and "Silent Knight" achievements

In the mission where you need to track down the Penguin on his ship (it is one of the first main missions in the game), after your encounter with Tracey (Penguin's assistant) and her goons, you will reach the first predator room in the game. Stay crouched, sneak up to an isolated enemy, and press Y to perform a silent takedown. Do this to all six enemies in the room, without being noticed, to get the "Anyone See That?" and "Silent Knight" achievements. Note: If you have already passed this point in the game, there are still plenty of other opportunities to get these achievements, but you should definitely do this before completing the story. After completing a predator room, the enemies will not respawn.

Easy "Flawless Display" achievement

Shiva is one of the Assassin's on the Most Wanted list. After playing through the story, go to the Gotham Merchants bank in "The Bowery" district. The starting point of Shiva's quest is not marked on the map. Listen for a crying baby, and inspect the abandoned baby stroller in front of the Gotham bank to begin this quest. You will then have to complete a series of tasks for Shiva. It does not matter if her ninjas or other enemies hit you while doing the tasks. After completing all the tasks, meet up with her in Sheldon Park (marked on your map). Successfully complete the fight with her without taking any damage to get the "Flawless Display" achievement. A good tactic to use to not get hit is to jump, hit an enemy once, and jump again. When jumping, the enemies will not have an opportunity to hit you. During the final phase of the fight, activate your Shock Gloves to defeat the enemies more quickly. If you get hit during the fight, pause the game, and choose the "Restart" option. The entire fight will start from the beginning, and you can try again. Note: It is possible to miss the Shiva fight in the story. If you miss the fight, you must start a new game and do Shiva's side quest to fight her.

Easy "Free Flow Fifty" achievement

You can easily reach a x50 combo in the first combat challenge, "Intensive Training". Enemies will not have armor or shields in this challenge. Reach Round 4 so there are enough enemies to build up a x50 combo. To ensure you do not get hit while fighting, perform a standard strike, then jump over an enemy, and repeat. None of the enemies will be able to hit you. It takes a little longer than countering and fighting the normal way, but it is much safer and easier to do. Do not perform any combo attacks or finishers -- so the enemies stay alive longer. If you have already unlocked the Shock Gloves, activate them to get a x2 multiplier with each hit.

Easy "One Of Each" achievement

There are five different gadgets needed to get the "One Of Each" achievement. They are all unlocked automatically while playing through the story. The following gadgets have to be used in one combo, without ever losing the combo multiplier:

1. Batclaw Slam: Press LT + Y, X.
2. Explosive Gel: Press LT + X.
3. Concussion Detonator: Press LT + B.
4. Glue Grenade: Press RT(2).
5. Batarang: Press LT.

Easy "Point Counter-Point" achievement

You will fight Deathstroke during a story mission, early in the game. Every time he attacks, you must press Y to counter him. Attack Deathstroke with Batman's normal strike. Doing so may initiate a QTE where you need to press the counter-button when it is displayed on the screen. If you press the button too early, or too late, your counter attack will fail, and you will get hit. If you get hit during the fight, pause the game, and choose the "Restart" option. The entire fight will start from the beginning, and you can try again. Note: It is possible to miss the Deathstroke fight in the story. If you miss the fight, you must start a new game and play until you reach the Deathstroke Boss fight to get the "Point Counter-Point" achievement.

Easy "Point To Point" achievement

To get the "Point To Point" achievement, you must use the Grapnel Gun and glide across the Gotham Pioneers Bridge (the large bridge connecting the south and north of Gotham City). You can do this at any point in the game while in Free Roam mode (even after completing the story). No upgrades are required. Start at one end of the bridge, and keep shooting the Grapnel Gun at the wires to stay above ground. After shooting the Grapnel Gun, you must also activate the Accelerator by pressing A(2) to avoid touching the wires. You may not land at any point while crossing the bridge. If you do, you must start over.

Green Arrow reference

In the interior of the Final Offer, in the same area as the "fight arena", there is a cargo container with "Queen Industries" on its side. "Queen Industries" belongs to Oliver Queen, a.k.a. the Green Arrow.

Harvey Dent reference

While in the G.C.P.D., up in the evidence locker you can see a newspaper clipping of Harvey Dent's win in the election for Gotham City D.A.

Rupert Thorne reference

In the G.C.P.D., look carefully at the bulletin boards in the squadron rooms. On the walls are newspaper clippings and mugshots with police reports. One of these reports references Rupert Thorne; another one of Gotham's infamous crime lords.
