Let me tell you a secret about 3jili that transformed my entire approach to the game. I used to struggle through missions, barely scraping by on normal difficulty, until I discovered the credit system's hidden potential. This isn't just another game mechanic—it's the core strategic element that separates casual players from consistent winners. The moment I understood how to leverage Operation Galuga's shop system, my win rate improved dramatically, and I want to share exactly how this works.

When you first dive into 3jili, the credit system might seem straightforward—complete missions, earn credits, buy upgrades. But there's an art to maximizing your earnings that most players completely miss. I learned through painful trial and error that playing it safe nets you minimal returns. The real credits come from embracing risk. Switching from normal to hard difficulty increased my credit earnings by approximately 40%, and activating one-hit kill mode—while terrifying at first—nearly doubled my mission payouts. That initial fear of losing quickly transformed into excitement as I watched my credit balance grow exponentially.

The shop interface initially overwhelmed me with choices, but I soon realized the upgrades fall into two distinct categories: quality-of-life improvements and game-changing transformations. The cheaper upgrades—expanding your health bar by 25%, purchasing extra lives, or starting with a preferred weapon—are affordable after just a few missions. I typically recommend new players invest in the health expansion first, as it provides the most immediate survival benefit. But the truly strategic decisions come when you're staring at those premium upgrades that cost 3,000-5,000 credits each.

I'll never forget the moment I saved enough for my first major purchase: the automatic weapon upgrade transformation. This single enhancement revolutionized my gameplay. Suddenly, every weapon I picked up became its superior version, effectively doubling my firepower throughout every mission. The difference was night and day—enemies that previously took multiple hits to defeat now fell with single shots. My mission completion times improved by roughly 30%, and more importantly, I started surviving encounters that would have previously ended my run.

What makes 3jili's system particularly brilliant is the limitation of equipping only two perks simultaneously. This constraint forces meaningful strategic choices rather than simply accumulating power. After securing the automatic upgrade, I faced a dilemma for my second slot: should I choose the perk that lets me keep my upgraded weapon after taking damage, or the one that preserves my weapon through death? I opted for the damage retention perk, reasoning that preventing weapon downgrades during intense firefights would provide more consistent value than recovery after death. This decision perfectly complemented my aggressive playstyle, though I've seen defensive players thrive with the death preservation option instead.

The beauty of this system lies in how it accommodates different approaches without declaring one objectively superior. During my 80+ hours with 3jili, I've experimented with numerous combinations, and what works best often depends on the specific mission parameters and personal preference. For boss-heavy levels, I might pair health expansion with weapon retention. For missions swarming with weaker enemies, I'll combine automatic upgrades with extra starting ammunition. This flexibility adds a layer of strategic depth that keeps the gameplay fresh across hundreds of playthroughs.

What many players fail to recognize is how these upgrades create positive feedback loops. Better perks lead to better performance, which generates more credits through riskier play, which unlocks even more powerful upgrades. I've tracked my performance metrics across 50 missions, and players who invest strategically in the shop system typically see their credit accumulation rate increase by 60-80% within their first 10 hours of gameplay. This isn't just gradual improvement—it's exponential growth that fundamentally changes what's possible within the game.

The psychological aspect shouldn't be underestimated either. Knowing I had powerful perks equipped gave me the confidence to attempt challenges I would have previously avoided. That confidence translated into taking calculated risks that paid off with substantial credit rewards. I went from cautiously navigating levels to aggressively pursuing bonus objectives and secret areas, all because the perk system provided both the tools and the safety net to experiment.

If there's one piece of wisdom I can impart to new 3jili players, it's this: stop treating the shop as an afterthought and start viewing it as your primary strategic tool. The difference between struggling through the game and dominating it comes down to how you leverage this system. Plan your perk combinations around your natural playstyle, but don't be afraid to experiment with approaches outside your comfort zone. The 15,000 credits I "wasted" on perks that didn't suit my style taught me more about strategic thinking than the 50,000 credits I spent on my preferred loadout.

Ultimately, 3jili's winning strategy isn't about reflexes or memorization—it's about understanding and mastering this elegant progression system. The credits you earn represent more than just currency; they're opportunities to reshape the game to your advantage. Whether you prefer methodical planning or aggressive action, the right combination of perks can transform 3jili from a challenging shooter into your personal playground of destruction and triumph.
