🗺️ Main Story Walkthrough

Aiden Caldwell arrives in the Villedor city outskirts searching for his sister Mia. The game's opening section in the Houndfield district doubles as an extended parkour tutorial — sprint, vault, and climb every obstacle to build the muscle memory for the game's fluid traversal system. Loot every Inhibitor Cache you see (marked on the HUD as glowing syringes); each one contributes to upgrading your Health or Stamina stat, which are the two most critical progression gates in the early game. Unlock the first GRE Anomaly encounter in this region to understand how the infected mutant system works. Connect with the Bazaar faction in the Fish Eye to begin earning Trust that unlocks Facilities.
The central mechanic of Dying Light 2 is assigning reclaimed Facilities (Water Towers, Electrical Substations) to either the Survivors or the Peacekeepers faction. Each choice changes what activates in the surrounding district — Survivors unlock safe house shortcuts and vendor access, while Peacekeepers deploy traps, zip lines, and later turrets. Water Towers must be climbed to the top and activated to clear the infected haze from the surrounding area, which in turn opens access to GRE Anomalies and Inhibitors in the zone. The Old Villedor region has 5 Water Towers and 3 Electrical Substations; assign at least 2 to Survivors early for Stamina Inhibitor locations.
The main story leads Aiden to the Bazaar faction at the Fisheye bar, then to the Nightrunner HQ and eventually to the Downtown district after crossing the VNC Tower bridge. Downtown is the most densely vertical environment in the game — complete all Airdrops (rooftop supply caches) to acquire upgraded gear sets and unique mods. The GRE Key storyline drives most of the main quests in this half; Lawan is introduced as a companion NPC at the VNC Tower. Stock Immunity Boosters (crafted from Chamomile and UV Mushroom) before beginning night expeditions — your Immunity Timer drains outside UV light and in GRE buildings.
Inhibitors are the primary vertical progression system and are found in GRE Quarantine Buildings, Military Airdrops on rooftops, and inside Forsaken Stores. Each GRE Quarantine Building contains 3 Inhibitors behind a time-pressure locked door sequence — sprint through the building to the main case, bypass the lock (hacking minigame), and exit before the timer expires. You need 3 Inhibitors per upgrade (Health or Stamina). Prioritizing Stamina upgrades first lets you chain longer parkour runs and hold block longer in combat. At max Stamina you can unlock the Double Jump and Air Kick skills, which dramatically open up traversal. There are 126 total Inhibitors in the base game; 30 are needed to max both stats.
Weapons degrade with use and cannot be repaired once their durability reaches zero, making Repair Kits and Weapon Upgrade slots the key economy to manage. Find Craft Masters (smiths) in safe houses and Survivor outposts who sell Blueprints for damage mods: Burning Mod (fire DoT), Toxic Mod (poison cloud on hits), and Electric Mod (stun on critical). The Immunity Boost consumable blueprint is obtainable from the Bazaar quartermaster early and should be crafted in bulk for nighttime activities. Military Medkits (found in Police Vans and Military Drops) are more efficient healing than crafted ones. At combat Level 4+ unlock the Stomp skill to finish down enemies on the ground, which is faster than repeated attacks.
Between 9 PM and 6 AM (in-game time) the infected become far more aggressive and Volatiles — fast, high-damage Infected — begin patrolling the streets. However, night is also when Renegades sleep at their checkpoints and Forsaken Stores with high-tier loot unlock. Avoid noise and keep a UV Flashlight equipped to deter Volatiles from charging. If you trigger a Chase, flee to an UV Lamp post or a night safe house to break the aggro. Nightrunner Tech items (Paraglider, Grappling Hook) are all obtained at night during story missions — the Paraglider is acquired at the VNC Tower mission and fundamentally changes traversal by enabling horizontal gliding between tall buildings.
The Wharf and Garrison districts are the final open-world zones before the game's linear endgame sequence. Both contain the highest-tier loot and the most challenging GRE Anomaly variants. Complete all Metro Stations in these districts to create fast-travel links for the endgame resource runs. The "X13" story mission leads Aiden to the GRE Supercontainer facility — bring maximum Immunity Boosters (10+) as the mission disables most UV lamp checkpoints. The final branching story choice here determines which ending you receive and affects which story companions survive the finale.
Completing the main story unlocks New Game Plus, which carries over all Inhibitor upgrades, weapon mods, and skills while resetting gear to the new NG+ loot pool, which includes Legendary-tier weapons with higher base damage and additional mod slots. Nightmare Difficulty (selectable at any time) dramatically increases infected health and lowers your Immunity Timer, making every GRE Building run a time-critical sprint. The GRE Anomaly encounters on Nightmare reward exclusive weapon blueprints not available on lower difficulties. Trophy-hunting players should note that the faction assignment choices lock out the opposite faction's side quests — a second playthrough is necessary to see all content.
⚔️ Boss Guides
Waltz
Attack Patterns
Waltz is the primary antagonist, a former GRE operative who has fully transformed into an infected but retained his intelligence and combat skill. He is encountered in multiple story confrontations throughout the game. His attacks include a rapid three-hit melee combo, a lunging grab that deals heavy damage if it connects, and a ground slam with a shockwave ring. In his final encounter he gains a charge ability that crosses the arena instantly. He does not spawn minions but the arena environment typically has hazardous elements like exploding gas canisters.
Strategy
Use the Perfect Dodge mechanic (dodge at the last possible frame before his strike) to trigger a slow-motion counter window and land 2–3 critical hits on his back. His lunge grab is telegraphed by a brief pause and shoulder drop — dodge sideways rather than backward. The Burning Mod on your weapon applies a DoT that persists through his attacks, adding passive damage during his active phases. Drink an Immunity Booster before the fight as the arena typically has limited UV light sources. The key mistake players make is trying to fight him aggressively — play reactively and wait for the perfect-dodge counter windows.
The Veronika Encounter (Hakon Storyline)
Attack Patterns
The Veronika encounter is a multi-stage story boss event tied to Hakon's questline in Old Villedor. It involves waves of Infected spawning in increasing numbers while Aiden must simultaneously deal with Renegade human enemies. The primary threat is the spawning Howlers, which call in additional Infected if not killed quickly. This encounter is partially scripted and partially combat-driven — survival depends on managing both the Renegade gunfire and the Infected horde simultaneously.
Strategy
Prioritize the Howlers first — each one silenced prevents an additional Infected wave. Use Molotovs in chokepoints where Infected funnel through doorways. The Renegade shooters are positioned on elevated walkways; use your Grappling Hook to close distance and knock them off ledges. Keep at least one Medkit in reserve for the story segment that follows immediately after this encounter. The outcome of the Hakon questline affects his availability as an ally in the finale.
GRE Anomaly — Revenant
Attack Patterns
GRE Anomalies are optional elite Infected encounters found after clearing Water Towers. The Revenant variant is the most common GRE Anomaly type. It has a three-stage health bar with a brief immunity phase at each transition. Its attacks include a rapid multi-hit claw combo, a ground-slam shockwave, and a teleport-dash that repositions it instantly behind you. At Stage 2 it gains a charged scream AoE that knocks Aiden back. At Stage 3 (below 33% health) it sprints continuously and its melee combo extends to five hits.
Strategy
Activate your UV Flashlight when it charges at you to trigger the stagger animation — this gives a 1.5-second attack window. During the immunity phase transitions, back away and drink an Immunity Booster if needed. The Toxic Mod is effective because the DoT continues during its immunity phase. Use the surrounding environment (parked cars, concrete barriers) to break line of sight during its Stage 3 sprint phase and reset the fight rhythm. Completing all GRE Anomaly encounters in a district is required for the Platinum trophy and rewards the highest-tier weapon upgrade components.
The Final Boss — [Story Spoiler: Lucas / X13 Facility]
Attack Patterns
The X13 facility finale involves a multi-stage encounter culminating in a transformation sequence. The transformed antagonist gains a massive health pool, a ground-pound AoE that covers half the arena floor, a ranged charged projectile, and the ability to spawn Viral-type Infected continuously. The arena has no UV light sources, making Immunity management the primary pressure throughout the fight. Platform sections require use of the Paraglider to navigate elevated areas and avoid the ground-pound AoE.
Strategy
Open the fight by using the explosive barrels positioned around the arena perimeter for significant burst damage. Use the Paraglider to reach elevated platforms when the ground-pound AoE becomes unavoidable at ground level. Attack the glowing infected weak points on the boss body for a 30–40% damage bonus. Drink Immunity Boosters proactively rather than reactively — the timer will drain faster than expected with no UV checkpoints in the arena. Keep your Grappling Hook available for emergency escapes from ground-level swarm situations.
