Huh, never heard of it before! From what I can see it kinda looks like an updated version of the Crossfire game?
Here's mine, using a fair share of Mushroom for the light buttons, the "Room" tiles are actually pretty great!
Yeah, I'd do the same, make it clear that if they see the HTR they fragged up. Have the them be Professional Rating 5 or 6, probably with a mage. And don't hesitate to shoot to kill, they probably have some Edge to burn and it'll be a lesson they'll remember.
One way would be to have him very differently with the runners compared to basically any other NPCs:
- Since he's head of security and he was raised by MCT he probably knows everyone in his team personally, maybe some of them would be people he'd call his friends. Maybe he has the occasion of saying goodbye to a colleague, and as he's one the verge of breaking down the colleague doesn't quite understand why he's making a scene since they've been saying goodbye for each other for 35 years now. Maybe he has a moment when he leaves the armory when he remembers all that happened here, maybe he refuses to leave without the drone that saved his life... You know, show that he cares about people, about places and things
- When he talks to the runners, have him be as cold as possible, if the runners argue or don't seem coordinated enough have him give snarky comments. If the runners' lives are in danger have him not care at all and leave them behind...
For that added bit of realism if you have metas in your group have him stop mid-sentence while saying some anti-meta comments, to represent how his son is slowly changing him.
The hardware is, which is the important part at scale: even if the code is 10x more expensive when you sell millions of the car it becomes pennies/car
