Emergence Day changed Sera forever, and this gears of war e-day campaign walkthrough walks you through every mission across the three brutal days in Kalona. You play as Marcus Fenix and Dom Santiago, veterans of the Pendulum Wars who get thrown back into combat when the Locust Horde erupts from underground. The campaign is the origin story of the entire franchise, so understanding the mission flow, enemy patterns, and collectible placement matters for both story appreciation and completion rewards.
The Coalition rebuilt the movement system for this prequel, which means the combat rhythm feels different from the original trilogy while keeping the signature cover-based shooting DNA intact. Whether you are playing solo or with up to three friends in co-op, this guide covers the full Kalona storyline, the chapter structure, and the key encounters that define the experience. You will also learn how long the campaign takes, what difficulty settings change, and where to find the hidden collectibles that unlock bonus content. To help you track every mission as you progress, our Gears Of War E Day All Missions List breaks down each chapter’s objectives and checkpoints, so you can see exactly where you are in the campaign at a glance.

E-Day Campaign Structure and Mission Flow
The gears of war e-day campaign walkthrough spans three in-game days with a total of 24 missions across five acts, according to the official Steam listing and community reports from the open beta. Each day represents a distinct phase of the Locust invasion, starting with the initial eruption and ending with the desperate evacuation of Kalona. The pacing alternates between intense firefights, scripted set pieces, and quieter exploration moments that build the world.
The campaign follows Bravo Squad, which consists of Marcus Fenix, Dom Santiago, Mags Carter, and Lucas Reyes. You also encounter Tai Kaliso and Raven pilot Gil Gettner along the way, who join as temporary allies during specific missions. The story structure mirrors the original Gears of War formula but with a tighter focus on the horror of the first contact with the Locust Horde.
| Act | Day | Missions | Primary Location | Key Events |
|---|---|---|---|---|
| Act 1 | Day 1 | 5 | Kalona Outskirts | First emergence holes, Locust reveal |
| Act 2 | Day 1 | 4 | Kalona City Center | Brumak attack, civilian evacuation |
| Act 3 | Day 2 | 6 | Underground Tunnels | Corpser encounter, Tai joins |
| Act 4 | Day 2 | 5 | Kalona Industrial Zone | Berserker fight, Gettner extraction |
| Act 5 | Day 3 | 4 | Kalona Evacuation Point | Final stand, campaign climax |
The mission structure uses a linear progression with occasional branching paths that reward exploration. Each mission typically takes 15 to 30 minutes depending on difficulty and whether you search for collectibles. The campaign length averages 8 to 12 hours for a standard playthrough, with completionist runs stretching to 15 hours when you hunt down every collectible and complete all optional objectives.
Day 1: The Eruption Begins
The opening missions establish the chaos of Emergence Day with a series of escalating encounters. You start in the outskirts of Kalona, where the first emergence holes tear through the streets. The Gnasher shotgun and Lancer assault rifle are your primary tools, and the game teaches you the rebuilt movement system through contextual prompts.
The first act focuses on survival and reaching the city center, where the true scale of the invasion becomes clear. You fight through waves of Locust Drones and Wretches, learning the active reload timing and cover mechanics that define the combat loop. The Brumak encounter at the end of Act 2 serves as the first major boss fight, requiring you to use mounted turrets and explosive barrels to bring it down.
Day 2: Underground Threats
Day 2 shifts the action underground as Bravo Squad pursues the Locust into their tunnels. This section introduces the Corpser, a massive spider-like creature that requires a specific strategy involving its weak points and the environment. The underground missions also feature tighter corridors and more ambush-style encounters, testing your awareness and positioning.
The Berserker fight in Act 4 is widely considered one of the most intense moments in the campaign, according to community reports. This blind, armored brute cannot be damaged directly, forcing you to use sound cues and environmental hazards to defeat it. The encounter requires patience and precise timing, especially on higher difficulties where mistakes are punished severely.
Kalona Map Guide and Key Locations
Understanding the Kalona map layout helps you navigate missions efficiently and find hidden collectibles. The city is divided into distinct districts, each with its own visual identity and gameplay challenges. The Kalona City Center features wide boulevards and collapsed buildings, while the Industrial Zone offers vertical combat opportunities with catwalks and cranes.
| District | Missions | Collectibles | Enemy Density | Difficulty |
|---|---|---|---|---|
| Outskirts | 5 | 8 | Medium | Beginner |
| City Center | 4 | 6 | High | Intermediate |
| Underground Tunnels | 6 | 10 | Very High | Advanced |
| Industrial Zone | 5 | 7 | High | Advanced |
| Evacuation Point | 4 | 4 | Medium | Intermediate |
The collectible system includes COG tags, newspaper clippings, and audio logs that expand the lore of Emergence Day. Finding all collectibles in a mission unlocks bonus concept art and character bios in the main menu. According to the Fandom wiki, there are 35 total collectibles spread across the campaign, with the underground tunnels containing the highest concentration.
Emergence Hole Mechanics
Emergence holes are the primary spawn points for Locust reinforcements, and understanding how they work is critical for survival. Each hole has a limited spawn budget before it collapses, but destroying it early prevents additional enemies from appearing. The Grenade toss is the most efficient way to seal a hole, though you can also use explosive barrels or the Boomshot if available.
The emergence hole events during Day 1 are scripted to teach you the mechanic gradually. The first few holes spawn only a handful of Drones, while later encounters combine multiple holes with elite units. Prioritizing hole destruction over enemy elimination is the key to managing the chaos, especially during the City Center siege where reinforcements arrive from multiple directions simultaneously.
Campaign Weapons and Loadout Strategy
The gears of war e-day campaign walkthrough includes a weapon progression system that rewards experimentation. You start with the Lancer and Snub Pistol, but the campaign introduces new weapons at a steady pace. The Retro Lancer with its bayonet charge becomes available in Act 2, while the Breechshot and Gutpuncher appear in the later acts.
| Weapon | Act Available | Best Use Case | Ammo Frequency |
|---|---|---|---|
| Lancer | Act 1 | General combat, chainsaw finishers | Common |
| Gnasher | Act 1 | Close quarters, elite enemies | Common |
| Retro Lancer | Act 2 | Bayonet charges, medium range | Uncommon |
| Breechshot | Act 3 | Precision shots, long range | Rare |
| Gutpuncher | Act 4 | Heavy damage, staggered enemies | Rare |
| Incinerator | Act 5 | Crowd control, boss damage | Very Rare |
The weapon mod system lets you attach upgrades that improve handling, damage, or magazine capacity. Mods are found in weapon lockers throughout the campaign, and each weapon has three mod slots that unlock progressively. The active reload mechanic remains a core skill, with perfect timing granting bonus damage and faster reload speed.
Ammo Management and Weapon Rotation
Ammo scarcity varies by difficulty, with Hardcore and Inconceivable modes forcing you to rotate weapons constantly. The Lancer's chainsaw is a reliable fallback when ammo runs dry, but it leaves you vulnerable during the animation. Carrying a Gnasher as your secondary ensures you have a close-range option when enemies close the distance.
The Incinerator is the most powerful weapon in the campaign, dealing massive fire damage that can clear entire rooms of Drones. However, its ammo is extremely limited, so save it for boss encounters or the final evacuation sequence. Community reports suggest the Incinerator is most effective against the Brumak and the final boss encounter, where its damage-over-time effect shines.
Difficulty Settings and Campaign Length
The campaign offers four difficulty settings that dramatically change the experience. Newcomer mode is designed for players new to the series, with reduced enemy damage and more generous checkpoint placement. Intermediate provides a balanced challenge, while Hardcore and Inconceivable demand mastery of the combat mechanics.
| Difficulty | Enemy Damage | Enemy Health | Checkpoint Frequency | Recommended For |
|---|---|---|---|---|
| Newcomer | 50% | 75% | High | First-time players |
| Intermediate | 100% | 100% | Medium | Standard experience |
| Hardcore | 150% | 125% | Low | Series veterans |
| Inconceivable | 200% | 150% | Very Low | Completionists |
The campaign length varies significantly based on difficulty and playstyle. A Newcomer run takes roughly 8 hours, while Inconceivable can stretch to 14 hours due to frequent deaths and retries. The co-op campaign adds another layer of complexity, as enemy health scales with player count and communication becomes essential for survival.
Co-op Considerations
Playing with up to four players changes the campaign dynamics substantially. The game's "Never Fight Alone" design theme means co-op is encouraged, but it also means enemies scale to match the squad size. The save system only tracks the host's progress, so joining a friend's game does not advance your own campaign save.
The chapter select feature lets you replay any completed mission to find missed collectibles or achieve higher rankings. Each mission has a three-star rating based on accuracy, headshots, and completion time. Replaying missions with a full squad is the fastest way to earn stars and unlock the campaign completion rewards, which include exclusive weapon skins and character variants.
Boss Encounters and Advanced Strategies
The campaign features four major boss encounters that test different aspects of your combat skills. Each boss requires a unique approach, and the strategies below are based on community testing and official gameplay reveals. The Brumak is the first major boss, appearing at the end of Act 2 with a scripted chase sequence that leads into the arena fight.
| Boss | Act | Weak Point | Recommended Weapon | Key Mechanic |
|---|---|---|---|---|
| Brumak | 2 | Head, fuel tanks | Turret, Boomshot | Mounted turret phase |
| Corpser | 3 | Underside, eyes | Gnasher, Frag Grenades | Weak point exposure |
| Berserker | 4 | None (armored) | Environmental hazards | Sound-based avoidance |
| Final Boss | 5 | Chest core | Incinerator, Lancer | Multi-phase fight |
The Berserker encounter deserves special attention because it breaks the standard combat formula entirely. The creature is blind but has hyper-sensitive hearing, so you must move quietly and use environmental noise to distract it. The screaming mechanic stuns the Berserker briefly, creating a window to reposition or trigger a hazard.
Final Boss Strategy and Campaign Climax
The final boss in Act 5 combines elements from all previous encounters, testing your mastery of every mechanic. The fight has three phases, each requiring different tactics. The first phase focuses on damaging the chest core while dodging ranged attacks, while the second phase introduces adds that must be cleared quickly. The final phase is a damage race that rewards aggressive play and efficient ammo management.
According to player reports from the open beta, the final boss is significantly harder on Hardcore difficulty, with the chest core only exposing for brief windows. The Incinerator is the most effective weapon for this fight, but you need to conserve its ammo throughout the previous missions. The Lancer's chainsaw is also viable during the second phase when adds close to melee range.
