I played some more Silent Hill Homecoming and beat the first boss. I did consult a walkthrough to do it. I would never have guessed the monster's weakness otherwise. Ironically, the very next time I restarted the boss battle, the loading screen also revealed that weakness.
Sean "Elysium" Sands on the Gamers with Jobs podcast recommended Mona: The Assassin, a professionally produced mod for Max Payne 2: The Fall of Max Payne. I'd already given away my PC copy of MP2, so I shut down Ubuntu, booted Windows, and downloaded it from Steam ($10 USD). I then downloaded and installed the mod, and played a half hour of it.
It has the same vibe as Max Payne 2, and all that good bullet-time shootdodging action. There are no plot-moving comic-book cutscenes, but that's understandable considering that this is a free mod. I'll be playing more of this in the future.
