This game has a Game Breaking Bug.

[Prime]

I only tried this twice on NG+ so I don't know if this bug happens too in normal mode.

After the fear toxin released via cloudburst, you'll have a mission to find Stagg in the airship.

The right way to do this mission is to land on the front of 2nd half-destroyed airship(where scarecrow stole the cloudburst and AK shoots you with a rocket launcher),go to the next room,take out some baddies and find Stagg.

Now, instead of doing those, if you go to the side entrance of the 2nd airship(where Batman glides from the 1st airship after Stagg is kidnapped), walk through Stagg's illegal experiment cell and when you try to enter the room where you were supposed to find Stagg, Batman will get stuck at the door. He can't move,he can't do nothing. If you restart the game,well it's hard to explain but Batman will walk in reverse(automatically and you can't control him) in the room and the militia will shoot you to your death.

The only way to fix this is either delete your latest save files or press jump/grapple repeatedly(this took many tries though). Hope the devs still read the discussion although it is unlikely. Either way, I don't find this glitch is too big of a matter, just don't follow the route from the side entrance of the 2nd airship.

Before deleting save files did you try backwinding your save to an earlier point, and if so what were the results?

lol, sorry. I did a mistake there. I didn't delete my save files but I backwind my save and it turns out alright.

I thought this sounded familiar :-)

haha. yeah it's mine. but yeah even when your backwind your save, if you do the same process the bug is still there. I wrote this so people don't do the same mistake.

Good thinking, Phantom.

The Stagg Airship trophies are usually the first full set I complete -- after testing the Voice Synthesizer at Panessa Studios and before the Cloudburst event -- because I hate waiting until the dust clears to collect the dropped crate trophy. On my next full playthrough I'll copy my save and I'll see if I can recreate that glitch, and find a possible workaround.

Alright man.

Glitch confirmed: when the Cloudburst first erupts I attempted access into Stagg Airship 2 by bypassing the forward entrance point, entering through the open side port. I just now had the same corridor entry bug as you.

It appears that re-enterIng Airship 2 during the Cloudburst event is specifically scripted to access from the front of the ship, probably because of the expository cutscenes during re-entry which can't be skipped. In the interest of science I had to backwind my own save, too. Thankfully I only lost about 2 minutes of progress. :-)

Phantom, good call. Good to know.
