When facing down endless Kaiju waves in N Country, the best power-ups ULTRA0 players can choose are Firing Speed Overclocks, Skill Cooldown Accelerators, and any upgrade boasting a Double or Triple Multiplier. Because PenGames’ hybrid shooter relies on an auto-lock-on targeting system, prioritizing rapid fire and frequent skill usage ensures Shirogane can clear the screen while you focus entirely on dodging. If you are wasting GEMs on raw attack power early in a run, you are mathematically setting yourself up for failure against the late-stage giant bosses of Area 81.
In a game that aggressively splits your attention between high-adrenaline arcade mechanics and a deeply integrated visual novel narrative, your build needs to do the heavy lifting. We have crunched the combat metrics to bring you the definitive tier list. Here is exactly how to optimize your run and survive the extinction-level threat.
Why Finding the best power-ups ULTRA0 Offers is Crucial in N Country
To understand why certain upgrades dominate the meta, you have to understand the architectural DNA of the game. Released in June 2026, the title revives the pseudo-3D shooter genre—think Space Harrier or Sin and Punishment—but injects it with modern roguelite upgrade paths and heavy visual novel elements. You are constantly moving forward into the screen, relying on the analog stick to weave through dense geometric bullet patterns.
Crucially, you do not manually pull the trigger. The game features an auto-attack system that engages the millisecond an enemy enters your targeting reticle. This fundamental design choice completely dictates the upgrade economy. In a traditional shmup, raw damage or spread-shots might rule supreme. Here, because you cannot manually lead your targets, firing speed acts as a proxy for accuracy. The faster you shoot, the more likely your auto-aim connects and secures a kill during a brief lock-on window.
A recent deep-dive into Target Lock Optimization reveals the underlying Pseudo-3D Combat Metrics. The data shows a stark preference among veteran players: Firing Speed 78% / Attack Power 22% when prioritizing upgrades. The core mechanics—Auto-Fire, Evasion, Smartphone UI, Skill Cast, and RNG Drops—all heavily favor speed over raw damage.
Furthermore, the narrative unfolds mid-battle. You are not just dodging lasers; you are reading. The smartphone-style UI at the edge of the screen displays real-time messages from your allies, ranging from critical tactical updates to casual banter that deepens character relationships. Because your cognitive load is split between surviving 3D bullet-hell patterns and reading story beats, you cannot rely on pinpoint precision. You need a build that plays itself aggressively, creating wide margins for error.
S-Tier: The Absolute best power-ups ULTRA0 Players Must Pick
When an item drops on the battlefield, you are immediately thrust into the RNG Upgrade Selection Matrix. You might see Option A: Firing Speed +15%, Option B: Attack Power +10%, or Option C: Skill Cooldown -2.5s. But the true game-changer is when the Triple Multiplier Effect Activated! notification appears, instantly overriding any standard tier list logic.
If you want to clear the hardest chapters, these are the S-Tier selections that should dictate your GEM spending and mid-stage choices.
| Power-Up Type | Base Effect | Multiplier Scaling | Tier |
|---|---|---|---|
| Rapid-Fire Actuator | +15% Firing Speed | Exceptional | S |
| Skill Capacitor | -2.5s Cooldown | Exceptional | S |
| The RNG Multipliers | 2x or 3x Any Stat | Game-Breaking | S+ |
Firing Speed (Rapid-Fire Actuator)
As established, auto-aim means every frame you aren't shooting is wasted DPS. Faster firing speed shreds Kaiju before they reach the bottom of the screen. When dealing with swarms of smaller, fast-moving targets, a slow, high-damage weapon will miss entirely as the enemies break your line of sight. Firing speed ensures that even a glancing lock-on results in lethal damage.
Cooldown Times (Skill Capacitor)
Skills are your one-button screen-clearers. Reducing cooldowns means more invincibility frames (i-frames) and more burst damage. In the later stages of N Country, the screen becomes so saturated with enemy fire that raw dodging becomes mathematically impossible. You have to use skills to phase through unavoidable damage walls. A build with maximized cooldown reduction turns your protagonist into an untouchable phantom.
The Double and Triple Multipliers
While not a base stat, the game’s RNG engine occasionally blesses an upgrade choice with a 2x or 3x multiplier. This is the golden rule of the game: if a Triple Multiplier appears, you take it. A 3x Attack Power boost will always mathematically outperform a standard 1x Firing Speed boost in the early game. It is the only time you should break from the established tier list hierarchy.
A-Tier and B-Tier: Rounding Out the best power-ups ULTRA0 Meta
Not every drop will offer an S-Tier stat. Knowing how to navigate the A and B tiers is what separates a doomed run from a clutch victory.
A-Tier: Attack Power (Kinetic Core Enhancer)
Raw attack power is undeniably useful, especially when ordered to take down an unknown giant Kaiju at the end of a chapter. However, it sits in the A-Tier because it often leads to "overkill" on smaller mob waves. Hitting a low-health enemy for 5,000 damage when they only have 500 HP is a waste of potential energy. It is a necessary stat for boss fights, but it should remain secondary to speed in your overall build.
A-Tier: Bomb Capacity (Area 81 Ordinance)
Bombs are your ultimate panic button. Having an extra bomb in your stock can single-handedly save a run when the screen gets too chaotic. They do massive area-of-effect damage and clear all enemy projectiles. The only reason this isn't S-Tier is that relying heavily on bombs means you aren't learning the enemy attack patterns, which will punish you in the endgame.
B-Tier: GEM Magnetism and Economy Boosters
GEMs are the in-game currency acquired by defeating enemies, used to purchase guaranteed items in the shop. Economy boosters are a trap for new players. Taking a GEM booster over a combat stat in Chapter 1 might yield a slight financial advantage, but taking it in Chapter 3 is a death sentence. By the late game, you need raw combat stats to survive; being the richest corpse in N Country does you no good.
Synergizing the best power-ups ULTRA0 Style: Shirogane’s Optimal Build
Mastering the battlefield requires understanding four key principles of the pseudo-3D engine. First, the analog stick controls raw movement, requiring constant repositioning. Second, auto-attack engages the moment a Kaiju enters the central targeting reticle. Third, you must maintain situational awareness because the smartphone UI on the screen edge delivers real-time lore without pausing combat. Finally, when trapped, activating a bomb clears the immediate hazard zone during overwhelming waves.
The protagonist of the first chapter, Shirogane, is an elite fighter stationed in the Area 81 unit. Her base kit is already tuned for high-speed engagements. To build her optimally, you must lean into her strengths rather than trying to patch her weaknesses.
Early Game Strategy: Prioritize Firing Speed and a single GEM multiplier if offered. Your goal is to turn her standard auto-attack into a wall of lead that melts the weaker early-game Kaiju before they can fire a single shot.
Mid Game Transition: Shift entirely to Cooldown reduction. Shirogane’s unique skills offer excellent mobility and burst damage. By reducing her cooldowns, you can chain her skills together, spending more time in i-frames and less time vulnerable to the increasingly complex bullet patterns.
Shirogane’s signature combat loop is a spectacle of efficiency. Her optimal sequence involves snatching a TRIPLE MULTIPLIER drop out of the air, dodging a lethal Kaiju strike by a fraction of a millimeter, and shouting 'Area 81, deploying payload!' before wiping the screen clean in a hyper-magenta flash.
Late Game Execution: Hoard your bomb capacity. The final encounters against the giant Kaiju feature screen-filling attacks that cannot be dodged conventionally. You will need a full stock of Area 81 Ordinance to brute-force your way through these damage checks.
While future episodic chapters will introduce new protagonists with different base stats, the "Speed-Skill" synergy pioneered by Shirogane remains the undisputed king of the current meta.
FAQ: Mastering the best power-ups ULTRA0
What are the best power-ups ULTRA0 has for absolute beginners? Beginners should heavily prioritize Firing Speed (Rapid-Fire Actuator) and Bomb Capacity. Firing speed makes the auto-aim mechanic much more forgiving, while extra bombs give you a reliable panic button when you misread a pseudo-3D dodge angle.
How do you trigger the Double or Triple Multiplier effect? The multipliers are governed by pure RNG (Random Number Generation) upon item drop. However, veteran players have noted that maintaining a high kill-chain and clearing waves quickly seems to slightly elevate the drop rate of high-tier items. Always check all three options before selecting.
Should I spend GEMs early or save them for late-game shops? Spend them early on guaranteed Cooldown or Firing Speed upgrades. The difficulty curve in N Country ramps up aggressively. If you hoard GEMs, you risk dying before you can spend them. An early stat advantage snowballs into an easier mid-game, allowing you to naturally accrue more GEMs later.
Does Attack Power affect Bomb damage? No. Bomb damage scales independently based on your overall level and specific ordinance upgrades. This is another reason why raw Attack Power sits in the A-Tier—it does not buff your ultimate panic button.
How does the smartphone UI affect combat decisions? The UI does not pause the game. When a message comes in, your eyes will naturally dart to the edge of the screen. This brief loss of focus is why Firing Speed and Cooldowns are S-Tier; they allow your build to maintain maximum DPS even when your attention is split reading critical story lore.
The Final Verdict
The harsh reality of N Country is that hesitation is death. You cannot out-damage a mathematically superior Kaiju wave with a slow, heavy-hitting build. You have to outpace it. By prioritizing speed, cooldowns, and capitalizing on RNG multipliers, you transform the game from a desperate survival struggle into a masterclass of arcade dominance.
