I included brief rules on amnesia in 2nd edition, but really don't like the old trope of needing a second blow to the head to recover (Heroes would just hit each other right away) and opted for a random duration instead.
Then the constrictor snake encounter just seems to come out of nowhere. I can't help but wonder if this was part of a larger story, but it was chopped down to fit three pages. Missing panels could have explained a lot more of this strange continuity.
The gorilla is recruited as supporting cast simply by being rescued (remember to make those recruitment checks, even if the players don't ask for them!).
Ray guns that kill motors are the oldest mad science trope in comics, so they don't need to come from 1970.
Dead Stick Landing was a stunt for aviators in 1st edition (and could be coming back in 2nd...).
By the way, it's extremely hard for one person to throw a net like that.
Before pointing out the impracticality of fighting in what Jane is wearing, keep in mind that the elemental is wearing a loose, baggy robe he could easily be tripping over.
