Alyx and Gordon head off for a subterrainien adventure to hunt down a suspected Combine Advisor lying hibernation in a local mine complex.
In this clip we see Alyx shoot a barrel that destroys a sign just as the player hits the ramp allowing them to complete the jump.
Took quite a bit of fiddling to get this right but now I'm sure that she'll hit the target 100% of the time.
Nice!
