Batman: Return to Arkham - Arkham Asylum

As mentioned in the other solution, playing on "hard" will unlock the other difficult-related achievements as well. Therefore, it is strongly recommended to play the game on this difficulty, since it is not hard at all. The fights are straight forward and most of the boss fights are easy, too.

Some tips I want to give you for your hard playthrough:

1. As you go through the game, collect as many collectibles as you can get. You'll get lots of XP and you will be able to upgrade faster.

2. When you upgrade Batman, focus on the combos and health upgrades first. Both will make fights a lot easier. Being able to us combos like + after a x5 combo will make the bigger fights easier. Health upgrades are especially useful in the latter boss fights. Don't wait to long to upgrade those. Personally, I found the gadgets upgrades to be negligable. They are more useful in the challenges, but that's just my way of playing the game.

3. The biggest challenge will be the boss fights. Every boss has a snag to himself. As soon as you found his weakspot, the fight will be relatively easy. I provided links to video guides in all the respective achievement solutions. If you get stuck in one particular fight, refer to the strategy mentioned in those videos.

Last but not least, I' ll provide a link to a playlist with videos of a full 100% hard walkthrough of the story down below.

This is for beating the game on Hard Difficulty, which will also unlock the achievements for beating it on Easy and Normal. You have the play the entire game on Hard, you cannot start at a lower difficulty and change it to Hard at the very end.

Hard is called this because you have no indicator when enemies are about to hit you (on Normal and lower they'll get lines over their head before they're about to hit you) and their hits take more of your health, so as long as you have a decent grasp of the countering system and pay attention to enemies' body language this really isn't that hard.

Something I haven't seen any guides mention is that when you use the Health Upgrade it instantly refills your health to full, so you should NEVER upgrade health until you're in a boss battle when you really need it.

What I highly recommend is when you start the game, go out of your way to get all the collectibles you can to get large amounts of experience, which you should in turn use to upgrade all your combat abilities and not health.

With your combat abilities upgraded to the max early on, it'll make Hard mode much easier as you'll be able to dispatch enemies quicker thanks to the Critical Strike ability and the Instant Takedown.

If you get all the collectibles you can, you'll likely have maxed out abilities and at least one available health upgrade by the time you get to Bane, which is arguably the hardest part in the game and where you will likely need to use your first Health Upgrade/Instant Full HP.

I recommend saving your remaining three health upgrades for:

-the Titan battle after you clean all three water tanks. This is tied with Bane for the hardest part in the game due to how small the arena is

-the Poison Ivy battle. Luckily you get a mid-battle checkpoint here but the second section is still very long and you will likely take too much damage

-the Double Titan battle before you face the Joker. This one isn't too bad but the level design will cause you to take some cheap hits. If you can pass this section without upgrading you'll have extra insurance in the final Joker battle
