I've gone through the level, turned on the generator, all that, but the gate that I am supposed to lead the big monster down doesn't open. I checked all the walkthroughs and done everything that they said, but the gate still doesn't open. Is this a glitch?
I think you are supposed to get on the train, and go at full speed towards the monster and then jump off. the train should slam the monster into the gate and blow it up, killing the monster in the progress
