Your Feature Request / Idea
it would be great if we could have acu troopers like in the film
While it is a good idea since it was in the movie, there are still some flaws to this. Consider this scenario IF in the event this is added.
If you encounter a dino-breakout, especially with a twister running around your park demolishing enclosure walls:
Would you:
A - Tranq the dinos using the ACU heli, takes less time.
or
B - Use ground ACU which takes 2x or maybe 3x the time needed to tranq a dino since you have to navigate through the terrain or park.
I bet majority would take option-A gameplay-wise. I don't think its worth the effort to develop & include ground-based acu, when there's already an airborne ACU that can do the job more efficiently.
