I'm sure I read something on the net about some spoilers for the next game or something like that... but all I saw was Joker beeing killed by himself and that's it. Well, you could hear him sing at the credits...but was there more? did I miss something?

For me it looks like: Joker = dead -> no 3rd game

joker isn't dead. it's the set up for third game where joker finally gets out of arkham city and into gotham.

This is our reply to those who have nuked us. It seems someone is desperate to have us nuked, but for what? Being new? You don't trust new things? Whatever, but don't make your personal issues our issue. Every group started at a first release and we have done nothing other teams haven't done yet. It doesn't matter what -grouptag is on a game, some things are needed to crack and release games, things have changed since 1999 FYI. Have a look at previous game releases and wake up.
We saw "securom.protection.not.removed_exe.taken.from.web_i44.tinypic.com.-xREL-.png"
It's not removed. It's bypassed. If this and only this is your complaint, and the end-user doesn't notice the difference, then what's the problem? We can meanwhile inform you that the contents of the files you blame us for stealing (BatmanAC.exe and BmLauncher) are IDENTICAL to those you obtain from any real activated original game. And there's more to it...
If you want to prove this to yourself you can "activate" the game with the "time server activation" option which executes with game first time you run it after install. Do this by installing game without applying crack. Now suddenly in your gamedir you have those two files whose contents are IDENTICAL to those of the release in P2P. What does this mean? It means we've stolen nothing. And it also means those files are not cracked. It's a kind of mislabelling calling their release a crack, it's just different executable files that you receive by clicking "Next". Unconditionally. For those of you who own the original or have an original installer, you'll notice that you can enter any serial at installation. That's because there's anyway no real activation. It's probably just some kind of mechanism to control release date for the game. We just simplified the thing by giving you those executables already downloaded, in case for example you don't have internet at the time of game installation and also to make setup process one step shorter.
Then perhaps you are now wondering how exactly did we crack the game if we didn't provide any *cracked* executables? Well, normally we shouldn't be as kind as to explain the mechanisms of our cracks, but this time we feel urged to do so. "securom.protection.not.removed" is technically speaking correct. It happens to be that all Securom based games we've checked so far load an executable file called gameservices.dll in the main exe's process. we could have integrated our code into main exe and you wouldn't even have noticed, but the option of automatically loaded .dll just made it smoother. It's not a generic .dll that works on all securom games, it's tailormade for this release and coded by us. If the .dll is present, which it isn't by default. From there you have access to what happens inside the main executable. If you can do a little bit of digital surgery you can trick the game to start. This also means that technically speaking, if you would like to, you could also probably - in a strict interpretation of the word loader - nuke us for using a loader. But that would be a very non pragmatic approach. Also it would leave a lot of releases by all groups vunrable for those tiniest of technicalities. Similar things have been done before with other groups, a famous paul.dll perhaps rings a bell?
That's also a funny thing about Securom: Try for example Lego Harry Potter 5-7 years. Modify the first instruction in paul.dll at OEP to: 0C3H or "ret" and you have bypassed the protection. (There might be some edition of this game out there where paul.dll isn't present) Then of course on top of that they added Securom media check, which isn't that silly easy to crack.
Enough of this. We could give you the entire manual on how to beat Securom, but that's not the point. Nevertheless, we'll be waiting for Securom to öturn offö the LoadLibrary ögameservices.dllö in their next release.
So. to sum it all up, you now know the details:
1) It can seem that we've stolen the exes and crack from web, but that's not the case.
2) If the game works (with that we mean game starts) then in our opinion there's no need to bitch about some small technicality.
And between, in case you guys didn't think about it: You're accusing us of stealing a crack that isn't even a crack. That's almost funny.

He's singing on a voicemail from 3 hours previous. I think he's really dead, since Rocksteady is following their own timeline, and Mark Hamill said he's done with the Joker. There's a lot of evidence that Scarecrow will be the main villain in the next game.

He seemed dead enough to me.
