One of the best ways to convey character (Black Mesa)

just a quick clip of some of the different dialogues in one of my favorite short but sweet scenes in Black Mesa, it's a very simple scene, but i think it really captures the guard's resilience against the marines by showing how he responds to the actions of them (almost every character has this of course, but i personally really like it here. Half Life was great at using show don't tell, and Black Mesa goes above and beyond with it.
Also if you're wondering, superbus via inscientiae is Latin for "Arrogance/proud in the way of ignorance" I honestly have no idea what that has to do with BMRF but im probably just stupid
Damn why did i write such a big description for a one and a half minute video?
