Look, let's be honest, the true crown jewel of the soulslike genre is the heart-pounding boss fight. While exploring vast, uncharted worlds has its charm, slogging through the so-called 'mobs' often exposes players to cheap traps and questionable design choices that test patience. So, for those who just want the heavy impact and white-knuckle tension of boss battles without the filler, here are five high-difficulty boss rush action games to try.

'Rubinite'is a top-down boss rush action game set in a dark fairytale world. Released in July of this year, it holds a 'Very Positive' user rating on Steam (with 4,111 reviews and 94% approval). Players step into the shoes of Rubypink, a princess on a bloody quest for vengeance to reclaim the homeland of the Scarlett Kingdom, locking horns with grotesque, blood-soaked monsters and an ancient religious order.

The core hook is the 'Focus' system, a rather neat combat mechanic. Instead of simply mashing attack buttons, Rubypink must target enemies for a set duration to expose their weak points before unleashing massive damage. Because winding up and casting takes time, precision dodging and split-second timing are mandatory. Absorbing power from fallen foes allows Rubypink to craft various talismans and tailor a bespoke fighting style, all wrapped up in a striking pixel art presentation.

Released in July 2021, 'Eldest Souls'is an action game chronicling a lonely crusade to slay the 'Old Gods' who brought a devastating famine upon humanity. It maintains a 'Mostly Positive' rating on Steam (4,436 reviews, 72% positive). Players wield an obsidian greatsword as a solitary knight, stepping up to the plate for brutal one-on-one duels against divine beings.

Combat revolves around snappy dash-dodges and weighty greatsword charges, demanding thorough pattern recognition since every boss dishes out unique bullet hells and attack strings. Every time a boss bites the dust, players absorb their essence to unlock fresh skills and perks, opening up plenty of build variety. On top of that, there are brief narrative segments for wandering around a 6-bit citadel, sniffing out hidden NPCs and side quests.

Launched in September 2024, 'NanoApostle'is an action game rooted in a dystopian sci-fi setting. It is enjoying 'Very Positive' reviews on Steam (1,302 reviews, 95% positive). The plot follows Anita, a young girl raised as a test subject deep within a grim secret laboratory, who teams up with Apostle, a sentient nanomachines lifeform, to bust out by smashing through cruel prototype bioweapons.

The combat tempo is brisk and refreshingly straightforward. Melee slashes, ranged projectiles, tight parries, and dodges weave together seamlessly to give reflexes a proper workout. The standout feature is the 'Destruction Point' system targeting weak spots; nailing these chinks in the armor at the exact right moment deals staggering damage to the boss. Multi-phase boss encounters that ramp up in complexity, combined with skill points earned from challenge tasks, make customising the action style quite rewarding.

Released in September 2024, 'Perennial Order'is a 2D dark fantasy action game set in a wild nature choked with bizarre flora and mutated beasts. It currently holds a 'Very Positive' rating on Steam (810 reviews, 92% positive). Visual immersion is top-tier here, courtesy of hand-painted oil-painting aesthetics and Lovecraftian boss designs.

The defining hook is the hardcore difficulty where a single hit spells instant doom. Naturally, observing boss wind-ups closely to sniff out safe zones and striking with surgical precision is the name of the game. It pumps up the tension significantly, and with local and online two-player co-op support, it is a cracking good time to share with a mate.

Released in November 2023, Kannagi Usagiis a 3D parrying action game starring a rabbit-eared miko protagonist. Boasting an 'Overwhelmingly Positive' rating on Steam (7,397 reviews, 97% positive), it punches well above its weight for a free-to-play title, delivering remarkably polished action mechanics.

The game essentially reinterprets the combat system of FromSoftware's masterpiece Sekiro: Shadows Die Twice. It faithfully captures that heart-stopping rhythm: clashing blades right as an enemy strikes for a parry, posture gauges, red kanji warnings for perilous sweeps and thrusts, and execution finishers. A total of eight distinct anime-style bosses await, and the thrill of chipping away at their increasingly aggressive patterns across two distinct phases is quite something.
