Leo System (HLVRAI)

an anxious black mesa scientist that gordon & the rest of the science team encounters in the rocket launch facility! andi gets recruited to help launch the rocket, then sticks around because gordon's tired of every scientist they encounter dying & andi not wanting to brave the dangers of black mesa alone.

andi's programming is bugged to where the flag of "i'm under attack!" gets constantly tripped, leading him to panic at random. this, combined with his lack of direction and inability to aim a gun, means he can be dead weight at times... although he makes up for it after stealing gordon's crowbar and getting Very good at beating aliens & soldiers to death.

he doesnt take the news of being an AI in a videogame well, and has an extended existential crisis that he never fully recovers from. he's very attached to the science team, and doesn't want their adventures together to end even if the game does.

he gets glitchy-looking when stressed out after learning he's in a game. its harmless, just looks weird and is a tell for when he's Doing Bad.
