The 1990s cartoons were defined by vibrant energy. Heroes were loud, villains often seemed ridiculous, explosions were frequent, and each episode seemed powered by sugar and electricity. On weekend mornings, you’d wake up early with a bowl of cereal on your lap, lost in shows like Rugrats, Doug, Hey Arnold!, Batman: The Animated Series, X-Men, Pokémon, and The Ren & Stimpy Show. This period also saw The Simpsons rise to pop-culture dominance and the emergence of Cartoon Network hits such as Dexter’s Laboratory. While Underling Uprising captures the neon-soaked, hand-animated aesthetic of 90s Cartoon Network, hits like Dexter’s Laboratory flipped the script on the ‘mad scientist’ dynamic. Instead of playing as the boy-genius in the lab, you are the mutant experiments themselves. It’s as if Dexter’s most volatile creations escaped the beaker, grabbed a giant weapon, and decided that teamwork and a lot of attitude were the only way to save the day.
Developed by Dummy Dojo (creators of Ninja Chowdown) and published by Abylight Studios, this hand-drawn beat ’em up arrives swinging with confidence, personality, and enough chaotic energy to power an entire arcade cabinet. Following the cult success of Ninja Chowdown, Dummy Dojo clearly knows how to channel nostalgia without being trapped by it. Underling Uprising may wear its inspirations proudly on its sleeve, but beneath the colourful cartoon exterior lies a surprisingly polished, mechanically satisfying brawler. This is not simply a retro throwback. It is a modern beat ’em up that understands why the genre worked in the first place.
Escape From the Mad Scientist
The setup is gloriously simple. Four genetically altered experiments known as the Underlings break free from the twisted laboratory of Dr. Baldrick, a villain so delightfully over-the-top he feels ripped straight from an old toy commercial. From there, the game launches players through seven increasingly ridiculous stages filled with mutant soldiers, robotic enforcers, alien monstrosities, and explosive set pieces.
The story is light, but it knows exactly what tone it wants. Conversations are packed with cheesy one-liners, cartoonish sarcasm, and playful banter that gives each Underling a distinct identity. One character is reckless and impulsive. Another leans into dry humour. Their interactions during levels make the adventure feel lively rather than simply serving as filler between fights.
What surprised me most is how much personality the game packs into relatively short scenes. There are even multiple endings and branching interactions depending on choices and character combinations, which gives replay runs more incentive than most arcade-style brawlers usually manage.
Combat That Rarely Slows Down
The real heart of Underling Uprising is its combat, and thankfully, it absolutely delivers. At first glance, it resembles the classic side-scrolling brawlers many of us grew up with. You punch enemies across neon-lit streets, juggle them into walls, smash objects for health pickups, and clear waves before progressing. The difference lies in how fluid everything feels.
The “Free-Flow” combo system gives combat a sense of improvisation that keeps encounters exciting from beginning to end. Rather than memorising rigid attack strings, you are encouraged to experiment. Launch enemies into the air, dash after them, slam them back to the ground, then chain directly into a special attack or an environmental interaction. It creates a rhythm that feels closer to a stylish action game than a traditional arcade brawler.
Each Underling also plays differently enough to matter. One focuses on speed and aerial mobility, while another specialises in heavier crowd-control attacks. None of them feel like throwaway alternatives. You naturally begin developing favourites based on playstyle.
The game’s greatest strength is momentum. Once combat clicks, you stop thinking about button presses and start reacting instinctively. Battles become fast-moving storms of explosions, flying enemies, and improvised chaos.
Importantly, enemies are designed to support that flow rather than interrupt it. Too many beat ’em ups rely on cheap stun attacks or frustrating knockdowns. Underling Uprising keeps aggression rewarding. Even difficult encounters encourage creativity rather than forcing defensive caution.
Hand-Drawn Style With Real Personality
Visually, the game nails its cartoon inspiration. Every stage bursts with exaggerated animation and vibrant colour. Streets glow with neon advertisements. Underground labs pulse with unstable machinery. Outer-space levels explode with purples, blues, and meteor showers that look ripped straight from a forgotten animated series pilot.
The hand-drawn animation deserves special praise. Characters stretch, squash, and react with genuine energy in combat. Attacks land with impact because enemies crumple, spin, or rocket across the screen in satisfying ways. There is a confidence to the presentation that many indie brawlers lack. The game never feels embarrassed by its silliness. It embraces every ridiculous mech suit, every dramatic villain monologue, and every absurdly oversized weapon with complete sincerity. That commitment gives the entire experience charm.
The soundtrack helps enormously, too. Electric guitars, synth-heavy themes, and punchy percussion keep every encounter moving at a frantic pace. Several boss themes genuinely sound like forgotten action cartoon intros from decades past.
Variety Keeps Things Fresh
One of the biggest problems with many beat ’em ups is repetition. Punching enemies for hours can quickly become exhausting if the game lacks mechanical variety. Fortunately, Underling Uprising constantly throws new ideas at the player. One moment you are brawling through city streets. The next you are racing through a high-speed hoverboard chase sequence, dodging explosions. Soon after, you are piloting a mech suit through waves of giant enemies, like a playable cartoon finale. These diversions could easily have felt gimmicky, but most of them are surprisingly polished. The vehicle sections control smoothly, the mech combat feels satisfyingly heavy, and the pacing benefits enormously from these tonal shifts.
The boss fights also stand out. Dr. Baldrick’s creations are wonderfully ridiculous, ranging from mutated beasts to towering robotic nightmares. More importantly, they require adaptation rather than simple button mashing. Learning patterns, avoiding environmental hazards, and timing counters become increasingly important as the game progresses. The later fights become genuinely intense, especially in co-op, where the screen often descends into total mayhem.
Best Played With Friends
Like the arcade classics that inspired it, Underling Uprising truly shines in multiplayer. With support for up to four players locally, the game becomes wonderfully chaotic with friends. Combo chains overlap, enemies bounce between players, and desperate revives during boss encounters create the kind of spontaneous moments that make couch co-op so memorable. There is an infectious energy to shared play sessions. People shout warnings, celebrate ridiculous combo chains, and laugh when someone accidentally launches an enemy into another player’s carefully planned attack.
The game also smartly avoids a common multiplayer problem by ensuring all players remain useful. Nobody feels like they are simply following the strongest character. The combat system naturally rewards coordination. Even the competitive Versus Mode feels surprisingly robust. It turns the combo system into a frantic battle of timing and positioning that works far better than expected.
A Few Rough Edges Beneath the Chaos
For all its strengths, Underling Uprising is not flawless. Camera readability can occasionally become messy in four-player sessions, especially when explosions and environmental effects stack on top of one another. Certain enemy types also rely a bit too heavily on armour mechanics that temporarily disrupt the otherwise smooth combat flow.
The story, while charming, never reaches the emotional highs its character moments occasionally hint at. There are glimpses of something deeper beneath the cartoon surface, but the game usually prioritises momentum over reflection. Some players may also find the difficulty spikes inconsistent in later stages. Boss encounters suddenly demand much tighter coordination than the earlier portions prepare you for. Still, these frustrations rarely overshadow the overall experience, as the core gameplay remains consistently fun.
Final Verdict
Underling Uprising succeeds because it remembers that beat ’em ups are meant to feel exciting first and foremost. Every mechanic, animation, and ridiculous set piece serves pure momentum and enjoyment. It captures the spirit of classic arcade brawlers while modernising the formula with fluid combat, excellent pacing, and enough variety to keep the experience fresh from beginning to end. More importantly, it has genuine personality. In a genre crowded with nostalgic tributes, Underling Uprising stands out for feeling alive rather than merely referential.
This is the kind of game that reminds you why local multiplayer became magical in the first place. Loud, colourful, chaotic, and packed with heart, Underling Uprising feels like discovering a lost Saturday morning cartoon that somehow evolved into a genuinely excellent action game.
