while i was replaying the game , i suddenly said to myself at the end of office [ before the jump in the elevator cage] that a fast zombie or two could make a good effect of surprise …
then reminding the hl2 monsters , the antlions could be very good in maps where player fight a chopper [ that should be ‘going to some random place to break the wall’ and stay near the impact zone ] as seen in hl2 before prison .
they could be coming from station exploded by jets , that can be a place where we see a scripted sequence . eyes following the plane , the the bombs and first thousands of antlions escaping the place
after i had a look at the fgd and saw these monsters are not used …may be you should add them in the fgd , at least in the coop mode they can be useful to spice the game , they are good enough to be added to your remodeled like they are [without the zombine but its a.i. can be good to have later] and loading them “costs” nothing .
i wonder how can look a gunship-drived by a vortigaunt ;’]
