Batman: Arkham Asylum Message Board  

ok I have collected the spores..and gottgen away from croK....but what do i do now....where do I go...(also forgot how to get into the batcave)......the map doesn't have any exclamation mark on it for me to go to.....the objective says"stop Joker from polluting gotham river".....help anyone plZ

Go back through the sewers, similar to to the way you first got to the batcave, it will lead you there.
Then once you're in the cave and have created the antidote, a custscene will appear.
Walk down to the main platform and turn left, using detective mode there should be a breakable wall.
Kick down a box so you can move, then use your ultra grapple on the breakable wall and pull it down.
Then you can progress to the next area.

Heres a handy guide too!

I just got stuck after that quest. I beat up the goon, got up the elevator and the quest just stuck and not progressing, the island is now empty (as well as all the mutated trees roots) and there is an invisible thing block my way to the garden (try the tunnel right next to it also get block) so I gave up.

Yeah, I heard about that problem, I restarted my computer when I got a graphics glitch similar to that.
I reckon just downloading the full release when it comes out will solve many problems... 😵

I bought the full version online on Amazon.com about a week ago and I am at the same point in the game and I am having the same problem. I do not know why people leave usless answers!!!
