Two marbles, double charged with as much as he can put into them safely- two throws. One blind but with a push of angle, probability, and Delta calculating trajectory? He flings that back into the alcove into the cracked open shell of the machine. The other? Eye on the ball, snapped at the crumpled form of Felix. Between Locus and Tucker? That guy was fucked- but a little extra boom has never, ever hurt a fight.

"Fire in the hole!" Warning more for Tucker than Locus- it shouldn't hurt that big, meaty monster all that much but- if he recognizes what he's saying? He'll duck aside. If not? It'll singe him a bit but he'll be fine.

All the momentum behind from the explosion, from his sprint, he follows right on through with the throw in a combat roll meant to bring him up to Tucker's side to provide covering fire in case that asshole decides to get back up again.
