The remaining aliens on the field must also be dead, but an exact number is impossible to determine.
Total dead: 74
If you would like some other opinions on the kill counts, you can try the EW kill count which is much lower. They seem to miss quite a few (and insert a knife killing in the bar brawl which wasn’t there.)
There is also the Carnage Counts YouTube channel this is a great deal more liberal than our counts mostly because they include cattle and horses and are a little more loose as to what counts as a kill (they counted a guy getting punched in the face a few times.)
