Let the horde gun keep up with the horde

The run ended on the second wave every time: the gun fired 6 flat rounds a
second, hit one body each, and every shambler soaked one — while hordeGrow
made each wave longer and denser. Doubled the rate and scaled it with the
wave (14/s at one set banked, 21/s at four), gave a round 0.5m of extra
reach, a wider cone, and enough damage to drop a shambler outright. Raised
the spawn rate to match, so surviving a wave still leaves a standing crowd
on your half — that pressure is the point of it.

Also: he no longer carries a second racket at his hip while holding one
forward (the run frames are the racket-less art), the umpire stopped talking
over himself and saying "remain seated" twice, and a timed freeze now shows
what it is counting down to instead of reading as dead controls.
