Although it shares plenty of similarities with Slayers Inc, the combination of multipliers reaching 500x, enhanced bonus mechanics, and a 15,000x maximum win gives Shadows Inc enough excitement to stand on its own. Overall, it’s another solid Hacksaw Gaming release, particularly for players who enjoyed the original.

Shadows Inc (Hacksaw Gaming) – Slot Review

Shadows Inc Hacksaw Gaming Slot Review Online Slots Casino New Volatile

Shadows Inc returns to the dark cyberpunk world of Slayers Inc, featuring masked assassins, rival factions, neon-lit streets, graffiti, and deadly combat. Its futuristic urban setting blends ninja-inspired action with Hacksaw Gaming’s gritty visual style.

Compared to Slayers Inc, the game retains much of the original’s identity, including the Slayer DuelReels and familiar bonus structure. Rather than completely reinventing the concept, Shadows Inc builds on the original formula with refreshed visuals and enhanced features, making it a familiar continuation for fans of Slayers Inc.

Shadows Inc is played on a 5×4 reel layout with 14 fixed pay lines. The game features high volatility, an RTP of 96.28%, and a maximum win capped at 15,000x your stake. Bets range from £0.10 to £50 per spin.

Shadows Inc Features & Mechanics

Slayer DuelReels

The Slayer DuelReels mechanic is activated when a VS symbol lands and its expansion would contribute to a winning combination. Once triggered, the VS symbol expands vertically to cover its entire reel, revealing two rival Slayers carrying different multiplier values.

The two Slayers then duel, with the surviving character’s multiplier applied to the entire reel, which also transforms into a full Wild Reel. Multipliers can range from 2x to 500x.

When multiple DuelReels contribute to the same winning combination, their multipliers are added together before being applied to the line win. If a VS symbol lands and activates on all five reels, the entire grid becomes Wild. Only one VS symbol can appear on each reel at a time.

Rise of the Syndicate

Landing 3 Free Spins Scatters triggers Rise of the Syndicate with 10 Free Spins. During this bonus, the chance of landing VS symbols is increased, creating more opportunities to activate Slayer DuelReels and their multipliers. Landing two additional Scatters awards 2 extra Free Spins, while three Scatters award 4 extra Free Spins.

Wild Slayers

Landing 4 Free Spins Scatters activates Wild Slayers with 10 Free Spins. Alongside the standard base game mechanics, landing a VS symbol has a chance to trigger the Slicer mechanic. When activated, Slicer selects a random horizontal row and fills the entire row with Wild symbols. Additional Scatters can once again award 2 or 4 extra Free Spins.

One Slayer to Slay Them All

Landing 5 Free Spins Scatters unlocks the premium One Slayer to Slay Them All feature with 10 Free Spins. This bonus retains everything from Wild Slayers but significantly increases the action, as both the Slayer DuelReels and Slicer mechanics are guaranteed to activate on every spin. This provides considerably more opportunities to combine full Wild rows, Wild Reels, and large multipliers.

Best of Bonus

The Best of Bonus symbol can upgrade any of the three main Free Spins features when it lands alongside the required number of Scatters. Landing it with 3 Scatters triggers Best of Rise of the Syndicate, 4 Scatters awards Best of Wild Slayers, and 5 Scatters unlocks Best of One Slayer to Slay Them All.

Instead of playing the selected feature once, the Best of Bonus plays it three times. The result from each round is recorded on a scoreboard, and once all three rounds have been completed, only the highest of the three results is awarded.

Conclusion

Shadows Inc delivers a stylish, high-volatility experience built around its Slayer DuelReels, expanding Wilds, and powerful multipliers. The three increasingly powerful bonus rounds provide plenty of variety, while the Best of Bonus mechanic adds an interesting twist by playing the selected feature three times and awarding the strongest result.
