Not the way I'm reading this:

There are three versions of the crap treatment, but they're almost identical to each other and I think they're all dated within a few days of each other.

It's pretty much what Alland describes, but toward the end there's dopey action (a Xenomorph version of the sheriff runs across throwing sticks of dynamite, etc.), and it wraps up with the spaceship completely buried, and Putnam having the attitude of "Well, they've got lots of air and food down there. Maybe in a few years we can dig 'em up and see how they're doin'."

Both the crap one and IT CAME FROM O.S. have all the same characters, the same everything; the crap one doesn't fall apart and become crap 'til the end.


So all four drafts are the same story, with the same charaxcters doing pretty much the same things, except that the fourth draft has a different title and action changes in the third act.
