Batman: Arkham Asylum

I found a couple of things on the Xbox 360 version (I have no knowledge about the PS3 or PC versions) so I just wanted to make a quick page about it in here. Feel free to edit it as you see fit.

Sequence skips

• When you need to protect your Batmobile, you need to fight a couple of enemies and then open the trunk and get the Explosive Gel. After you retrieved the item, you need to go into Detective Mode and scan the area for a clue. It's not necessary to scan the area for a clue, you can immediately go to the Medical Facility building.

• After you've visited Poison Ivy the first time in the Botanical Gardens, you actually need to go to the Arkham Mansion and talk to Cash. This isn't needed. When you get out of the Botanical Gardens you can immediately go to Arkham North and use the Grappling Line to enter the Intensive Treatment building from the top (You'll see 3 Jabbermouth's there). Normally when you would've talked with Cash there's a red guy up there (You know, those guys you need to stun first), but if you don't visit Cash the red guy isn't there.

Possible useful tricks/sequence breaks

• Unfortunately I can't record from a console so I'll have to describe it... In Arkham North, I tried to jump from the roof on the left of the Intensive Treatment building onto the place with spikes on the edges to enter the building from the top. You can walk a little bit next to the chimney there but there's a little invisible wall blocking you from getting more onto the roof. In some way I got Batman to jump kind of around the invisible wall onto the roof part, and from there I could jump on the higher place to enter the building. I did this after I visited the Batmobile so the trick was done early in the game (And had no effect at this point, nothing different was triggered in the building). Perhaps when you try to do this trick later on, the triggers inside the building (To go to Croc's Lair) could already be present (Depends if the programmers were lazy of course ;)). Problem is, the trick is extremely tricky. I did it once by accident, and I haven't been able to reproduce it ever since.

• I just remembered another thing that's also possible but didn't prove useful because of the lack of the Grappling Line (And Triple Grappling Hook). It's in the Sewers part after you've been to your Batcave for the first time. Then you get in this rather big part where you need to normally climb around (Can't use the Grappling Hook because the place is falling apart). Near the top of it there's a big gap with a Riddler's Trophy on the opposite side. Just a little before this part you can climb around a corner to get in a small space in a pillar to grab a Riddler's Trophy and scan the ? riddle. From that place you can jump out and fly to the opposite side with the other Riddler's Trophy. Unfortunately you can't procede because of the other big gaps up there. And even if you could, you would still need the Triple Grappling Hook to destroy the wall high up there. So I'm afraid it's useless but I thought I should mention it anyway.
