Mortal Oath (Foxhound Games) – Slot Review
Mortal Oath by Foxhound Games embraces a dark fantasy theme rooted in demon-hunting mythology and cursed warrior lore. The setting portrays a grim battlefield where corrupted hunters clash with supernatural forces, combining Eastern-inspired weaponry such as katanas with gothic elements like hell gates, ancient statues, and foreboding relics.
The visual style relies on deep shadows, glowing runic details, and menacing character designs to build a tense and dramatic atmosphere. Rather than focusing on exploration or treasure hunting, the game centres on themes of sacrifice, power, and relentless combat. Expanding hunters and multiplier-driven mechanics reinforce the narrative of warriors forging dangerous pacts, resulting in a cinematic presentation that aligns with Foxhound Games’ darker, high-intensity design approach.
Mortal Oath features a 5-reel, 3-row layout with 9 fixed pay lines, delivering a high-variance experience with a 96.32% RTP and a maximum win potential of 10,000x the stake. Bets range from £0.10 to £100.
Mortal Oath Symbols & Pay Table
The game includes 13 symbols in total, consisting of six low-value icons such as coins, scrolls, katanas and helmets, alongside three premium demon characters in yellow, blue and green variations. Additional special symbols include the Wild, Corrupted Hunter, Demon and Bonus Scatter. The Wild symbol is the highest paying, offering up to 20x for five across a pay line, and substitutes for all regular symbols while appearing only in the base game.
Mortal Oath Features & Mechanics
A key feature of the base game is the Corrupted Hunter. These symbols function as expanding Wild reels when doing so creates a winning line. Upon expansion, each Corrupted Hunter reveals a random multiplier and three empty stacks. Every time it participates in a win, one stack fills, and once all stacks are completed, a dedicated respin is triggered with the Hunter remaining sticky while the other reels spin again. Multiple Hunters can appear simultaneously, with their multipliers combining when involved in the same win. Demon symbols act as premium icons during the base game, but their multiplier potential becomes active only within the bonus feature.
The Night of the Hunt bonus is triggered by landing three Bonus Scatters. During this mode, regular symbols are replaced by bonus feature elements that progressively build a Total Multiplier. Bonus Demon symbols land with pre-set multiplier values and remain sticky, while additional mechanics such as the Collector, Gun Ability, Gates of Hell and Guardian Statue introduce layered progression. These features enhance multipliers, modify symbol values and can reset spins or trigger powerful effects like Divine Retribution, which doubles all Demon multipliers and restores lives once per bonus round. The bonus continues until all lives are exhausted or the grid fills entirely with Demon symbols, potentially awarding a significant multiplier boost before the final pay out is calculated.
Conclusion
Mortal Oath by Foxhound Games delivers a dark, high-volatility experience that leans heavily into intense combat mechanics and multiplier-driven gameplay. The Corrupted Hunter feature and evolving bonus round create strong win potential, though the pace and variance mean it may feel unforgiving during quieter sessions. Visually and mechanically, it stands out with its gritty fantasy tone and layered features, making it a solid choice for players who enjoy riskier slots with dramatic, progression-based bonuses rather than casual, low-stress play.
