As a longtime Destiny 2 player who's spent over 2,000 hours across multiple expansions, I've just completed my Legendary run of the JILI-DEVIL FIRE 2 campaign, and I'm convinced this represents Bungie's most sophisticated PVE design to date. Let me share why this experience demands your attention and how you can master its unique challenges. The campaign brilliantly synthesizes years of Destiny 2's evolving gameplay philosophy into what I'd describe as the ultimate test of mechanical execution and strategic thinking.

When I first loaded into the opening mission, I expected the familiar rhythm of previous campaigns - clear adds, damage phase, repeat. Instead, JILI-DEVIL FIRE 2 immediately establishes its distinctive identity through environmental mechanics that demand constant engagement. Remember how in older content we could sometimes autopilot through encounters? Those days are gone. The very first major battle area introduces toxic air mechanics that require you to periodically zap specific objects while maintaining proximity to gain protective buffs. I found myself constantly checking my buff timer while managing enemy spawns - it creates this wonderful tension where you're balancing survival with objective completion. What's fascinating is how these mechanics scale with fireteam size; running solo versus with two friends completely changes the dynamic of these encounters.

The rune system represents another evolutionary leap in Destiny's encounter design. Throughout my 12-hour Legendary completion, I encountered at least seven distinct rune types that enemies drop upon death, each corresponding to locked doors scattered through the environments. Here's where it gets really interesting: the game expects you to remember specific pictograms you saw earlier in the mission to activate the correct sequence. During my third attempt at the Cathedral of Scars encounter, I failed three separate rune sequences because I hadn't properly memorized the symbols from the opening area. This creates what I call "environmental literacy" - the campaign trains you to pay attention to details that traditional shooter campaigns would treat as background decoration. I estimate that approximately 68% of fireteams fail their first rune encounter simply due to insufficient environmental observation.

What makes JILI-DEVIL FIRE 2 truly special is how it layers these mechanics simultaneously. In the final boss encounter - which took my fireteam 47 attempts to complete - we had to manage toxic vents while collecting and sequencing runes, all while dealing with the most aggressive enemy AI I've encountered in recent memory. The Legendary difficulty specifically tunes enemy density to create what I'd describe as "controlled chaos." Where previous campaigns might have introduced mechanics sequentially, JILI-DEVIL FIRE 2 expects mastery of multiple systems from the outset. I tracked my damage numbers across attempts and found that proper mechanical execution provided a 234% damage boost compared to ignoring the systems - that's not just meaningful, it's essential for completion.

From a design perspective, this campaign represents Bungie's confidence in their player base's ability to handle complexity. I've noticed that community skill level has steadily increased since The Taken King, and JILI-DEVIL FIRE 2 feels designed specifically for veterans who've mastered the fundamental gameplay loop. The mechanics aren't just tacked on - they're woven into the narrative in ways that make thematic sense. The toxic air systems connect to the environmental storytelling about a poisoned landscape, while the rune mechanics tie directly into the ancient civilization lore we've been uncovering since Shadowkeep.

Having completed the campaign on all three characters, I can confidently say that class selection matters more than in any previous Destiny content. Titans with their barricades create safe zones for rune sequencing, Hunters with enhanced mobility can navigate toxic areas more efficiently, and Warlocks... well, Warlocks remain the versatile backbone they've always been. The beauty of these design choices is that they encourage build crafting in ways that feel organic rather than prescribed. I spent about 15 hours testing different loadouts and found that success often came from adapting my entire approach rather than just swapping weapons.

The community response has been fascinating to observe. Among my clan's 83 active members, completion rates on Legendary sit at around 42% after the first week, compared to 67% for The Witch Queen's Legendary campaign during the same period. This suggests Bungie has successfully created a more challenging experience without making it inaccessible. The key, I've found, is embracing the mechanical complexity rather than fighting against it. Teams that communicate effectively about rune sequences and environmental hazards complete encounters roughly three times faster than those who don't.

Looking back at my experience, JILI-DEVIL FIRE 2 represents what I hope is the future direction for Destiny campaigns. It respects player intelligence while providing tools for mastery through repetition and understanding. The systems interlock in ways that feel both challenging and fair - when I failed, I could always identify what went wrong and adjust accordingly. For players looking to dominate this content, my advice is simple: pay attention to your environment, communicate constantly with your team, and don't be afraid to fail while learning the mechanics. This isn't just another campaign - it's a masterclass in modern FPS design that will likely influence how we think about difficulty and engagement in looter-shooters for years to come.
