SUREFIRE Strike Hard With ‘Mercy Kill’ As They Unleash New EP ‘Endorphins’

Milwaukee metalcore force SUREFIRE deliver a crushing new lyric video for “Mercy Kill,” featuring Kyle Medina of Bodysnatcher, marking the release of their new seven-track EP Endorphins. The track stands as one of the EP’s most aggressive moments, blending unrelenting heaviness with a raw emotional charge that hits with immediate force.

“Mercy Kill” is driven by bone-snapping riffs, punishing breakdowns, and venomous vocal exchanges that leave no room for restraint. Kyle Medina’s feature amplifies the track’s hostility, adding a brutal edge that perfectly complements SUREFIRE’s metallic hardcore foundation and reinforces the song’s confrontational energy.

The lyric video keeps the focus locked on impact and message, pairing stark visuals with the song’s intensity to underline its themes without distraction. Every word lands with weight, allowing the aggression and emotion to cut straight through.

With Endorphins, SUREFIRE solidify their position within Milwaukee’s heavy underground, delivering a release that is concise, volatile, and unapologetically heavy. “Mercy Kill” serves as a clear statement of intent — this is a band operating at full throttle, channeling rage, precision, and momentum into one relentless surge.
