Mortal Oath

Mortal Oath: The Hacksaw Gaming Build

This version of Mortal Oath is the release distributed through Hacksaw Gaming, built on the same dark Sengoku-era foundation as the original Foxhound Games title but configured with its own settings — most notably a medium-volatility profile rather than the higher-volatility build found elsewhere, plus a distinct 5x3 reel layout with 9 fixed paylines.

Theme and Setting

Mortal Oath is set during a supernatural take on Japan's Sengoku era, a period of civil war and social upheaval reimagined here as a battlefield haunted by demons and divine forces. The presentation favours a bleak, windswept aesthetic — coins, scrolls, blades, headgear and demon figures fill out the paytable, all styled to reflect a tense, war-torn world rather than a bright, celebratory one. Fire, tension and spiritual conflict run through the visual design throughout.

How This Build Plays

Winning combinations form by landing three to five matching symbols left to right across the 9 active paylines. This configuration runs on a comparatively steadier, medium-volatility math model, meaning the bigger swings are somewhat smoother here than in higher-volatility builds of the same title, while still offering genuine feature-driven upside through the Corrupted Hunter mechanic.

Corrupted Hunter Expanding Wild

The Corrupted Hunter wild remains the centrepiece feature: it substitutes for all regular symbols, and whenever it forms part of a win it expands to cover the whole reel, revealing a random multiplier of up to 100x along with three stack meters. Each win it contributes to fills a stack, and once all three are full, a sticky respin sequence kicks in with the Corrupted Hunter locked in place, offering a genuine chance at a substantially bigger result. A separate Night of the Hunt bonus round can also be triggered from the base game, starting with three lives and populated only by bonus feature symbols or blanks — landing Bonus Demon symbols increases the round's overall multiplier before the accumulated total pays out once lives run out.

RTP and Max Win

This build returns 96.3% to players at its top setting, matching the strong RTP of the wider Mortal Oath release, alongside a maximum win of 10,000x the stake. Stakes here run from 0.10 up to 100 per spin.

Verdict

This Hacksaw Gaming configuration of Mortal Oath offers the same striking demon-hunter theme and Corrupted Hunter mechanic as the original build, but with a comparatively gentler medium-volatility setup that may suit players who want the feature depth without quite as extreme a variance.
