Gears of War: E-Day Horde Siege Guide

Horde Siege is Gears of War: E-Day’s 12-player PvE mode. Three COG squads share a large Kalona battlefield, but each squad enters with its own mission and can cross paths with squads already in progress. Your group selects a class, playlist, and difficulty; completes assigned R.I.G. objectives; gathers shared Energy; takes optional risks for supplies and Weapon Parts; then clears an extraction zone and boards a Raven.

This hub describes the launch framework announced by The Coalition for Steam base-game AppID 3010850. The Multiplayer Beta uses separate AppID 4059240 and offers only a subset of launch content. Beta balance, matchmaking, map availability, and progression behavior must not be treated as permanent launch rules.

Understand the three-squad battlefield

Horde Siege is not one twelve-person unit following a single wave script. It places three squads on the same larger map. Each squad works through its own mission while other squads influence the battlefield. You may encounter fortifications, equipment, or consequences left by a squad that fought in the area earlier.

The official design emphasizes a persistent battle rather than a private arena. That creates three layers of responsibility:

• Personal: use your class, weapons, equipment slot, and cover well.
• Squad: share information, protect squad lives, choose Energy investments, and complete your assigned objective.
• Battlefield: respond when an Invasion Event affects all squads or when helping another squad creates a safer route.

The Beta names Golden Quarter as its Horde Siege map. The Coalition says the base game will launch with three Horde Siege maps in total, with more planned after release, but the other launch map names were not public at this checkpoint.

Pick a mission length before a difficulty

The three main playlist types solve different time and intensity needs. Blitz is described as a short mission with one or two objectives and an expected duration around 15–20 minutes. Siege allows more traversal and multiple objectives, with a stated 20–40 minute range. Horde asks the squad to defend one position through ten waves with limited support and can run 50–60 minutes.

Those are official expectation ranges, not timers or guaranteed completion lengths. Matchmaking, modifiers, squad readiness, failures, and optional events can extend a run. Choose the playlist whose worst reasonable overrun still fits the group’s session.

Difficulty is tied to class progression. The game recommends a level range, but the squad makes the final choice. Infantry is aimed at experienced players around class levels 10–20, Commander at levels 20–30, and Allfather at max-level classes. A lower onboarding setting also exists for learning. Higher rewards do not make a difficulty efficient if the squad repeatedly loses its lives before extraction.

Learn the five R.I.G. objective families

Most launch missions revolve around Resonation Imaging Geographers—mining scanners repurposed to map Locust tunnels beneath Kalona. The announced objective set gives the squad a quick way to predict its next pressure:

• Secure: enter and clear a Locust-held position.
• Calibrate: defend a sequence of nearby zones so a R.I.G. can map accurately.
• Repair: recover scattered components and reinstall them.
• Defend: hold an active R.I.G. until its scan completes.
• Horde: protect a single R.I.G. through ten escalating waves.

Objective names tell you the job, not the exact route. On arrival, identify the interaction point, the enemy approach lanes, safe revive paths, a resupply option, and where the squad can regroup if the objective shifts.

Spend shared Energy without wasting squad value

Objective completion and enemy kills add to a shared squad pool of Energy, but purchasing is individual. Supply Caches can offer equipment, grenades, weapons, and Squad Perk upgrades based on class and progression. Defensive positions can also use Energy to buy or upgrade turrets, and some turrets can be detached as Heavy Weapons.

Because earning is shared while spending is personal, speak before an expensive purchase. A strong order is survival need first, objective tool second, and luxury replacement last. Buying another weapon while a squad lacks revive control or objective defense can leave everyone weaker even if the purchase improves one player’s score.

Energy also contributes to mission score, so hoarding everything is not automatically optimal. The decision depends on what remains between the squad and extraction. No fixed “best spend” table is published because cache options, class unlocks, modifiers, and balance can change.

Take optional rewards with an exit plan

Secondary Objectives can award Weapon Parts, equipment, and Squad Perks. Public examples include defusing explosives, eliminating high-value targets, collecting COG intel, and delivering a Power Core to another squad’s R.I.G. COG Resupplies may appear as Supply Drops, Perk Caches, or Weapon Part Stockpiles, but attracting Locust is part of the tradeoff.

Weapon Parts have lasting value because they unlock Weapon Mods after the relevant class-level milestone. However, parts collected in the mission are kept only if at least one member of the squad extracts successfully. An optional detour that leaves the last survivor too far from the landing zone can erase the exact reward the group chased.

Use a quick risk test before detouring: remaining squad lives, current ammunition and equipment, distance to the main route, active modifier, and time needed to return. If several are unfavorable, complete the main mission first.

Survive Invasion Events and squad wipes

Mission Modifiers can change combat rules, while Poisons strengthen the enemies assigned to a squad after boss waves. Invasion Events affect the broader map and can introduce large Locust such as a Corpser or Brumak alongside a temporary battlefield restriction. The official examples include blocked extraction or disabled Supply Caches.

When a player dies, they drop COG tags. A squadmate can bring those tags to a Supply Cache to revive them, while a player from another squad can pick them up for an immediate revive. If the entire squad is killed, it consumes a squad life. Losing every squad life ends the mission and returns the group to the lobby with partial XP.

The practical recovery rule is to regroup before the second rescue attempt. Repeating the same exposed route turns one downed player into a squad wipe. Stabilize cover, clear the closest threat, name who has the tags, and protect the delivery path.

Extraction is part of the build, not a victory lap

After the main objectives, the squad must clear a landing zone and survive for the Raven. Technically, only one squad member needs to board to complete the mission. That does not make abandoning teammates the default strategy; it establishes the minimum recovery condition when a run collapses.

Save enough ammunition, equipment, and mobility for this phase. Weapon Parts are not secured until successful extraction. If an event blocks extraction or caches, reassess the route rather than assuming the normal exit sequence is active.

Connect classes, mods, and progression

The launch class set is Assault, Breacher, Marksman, and Medic. Each has a starting loadout, combat bonus, Tactical Gear with a cooldown, and thirty levels of progression. Level milestones unlock weapons, equipment, Armor Mods, Tactical Gear Mods, and Weapon Mods. Health and damage increases also occur at key class milestones.

There is no mandatory one-of-each composition. The Coalition explicitly permits duplicate classes. The decision should come from the mission and squad: sustained midrange control, close-range breach pressure, long-sightline precision, and wide-area healing/revival are different tools, not a permanent tier list.

Start with the Horde beginner guide for a first-mission sequence. Use the Classes hub when choosing a role and the Arsenal hub to separate Horde mods from the unmodded Versus sandbox.

Horde Siege FAQ

Is Horde Siege twelve players in one squad?

No. It is a twelve-player battlefield built around three COG squads, each with its own mission.

Do Weapon Parts remain if the squad fails to extract?

Parts collected during a mission require a successful squad extraction to be kept. At least one member must make it out.

Is Golden Quarter the only launch map?

It is the named Beta map. The Coalition has announced three Horde Siege maps for launch but had not publicly named the other two as of August 8, 2026.

Which class is best?

There is no official universal best class. Mission type, sightlines, difficulty, unlocked mods, and squad composition change the answer, and Beta impressions are balance-sensitive.
