May need to copy/paste that.
It is a very simple procedure:
NOTE: HMT 3.5 and Phenomena's 60 plugin pack are required.
First, open up a map with the infection form in it in HMT 3.5
Then, browse to [bipd]Biped, the fourth(4th) down from the top.
Now, select the infection form tag.
In the first large set of check boxes, uncheck the first in the second column, "Destroyed After Dying".
Then go down to where it says "More Flags" (which is under Camera Field of View, just a bit below the first set of check boxes.)
Uncheck the seventh(7th) box in the first column, which says "Has No Dying Airbourne".
Note that you can leave the check box "Destroyed After Dying" checked. If you shoot an infection form on the ground it will pop like it normally does. If you shoot it in midair it will hit the ground, flop, then disappear once it comes to rest. If you unchecked Destroyed After Dying, then if you shoot an infection form on the ground it will freeze its position, but more often than not it will look cool. As you can see in the pictures it does get kinda weird sometimes where the body is still sort of standing.
