How Does Horde Siege Gameplay Work?
A standard match begins with three four-player squads deploying into the warzone. Squads operate independently while pursuing assigned objectives.

- Squad Setup: Up to 12 players split into three squads of four.
- Loadout Selection: Choose your class, weapons, and tools to build a balanced squad layout.
- Map Deployment: Enter massive Kalona maps. Three maps are available at launch, including Golden Quarter.
- Mission Execution: Complete primary objectives while navigating shared battlefields.
- Resource Loop: Complete side tasks, earn Energy, and purchase powerful gear and turrets.
- Boss Threats: Survive terrifying Invasion Events featuring legendary bosses like Corpsers and Brumaks.
- Extraction Phase: Reach the landing zone, defeat remaining enemies, and board the Raven chopper.
- Victory Condition: Only one surviving squad member needs to board for a successful extraction.
- Drop-In Support: Join ongoing matches seamlessly. Retreated squads may leave behind helpful turrets and loot.
Core Horde Siege Gameplay Loop: Choose your class → Pick a playlist and difficulty → Complete objectives and side tasks → Manage Energy and resources → Successfully extract.
Master Key Mechanics of Horde Siege
Understanding core mechanics keeps your squad alive during brutal operations. Use these foundational systems to maximize your extraction odds:

- Death & Revives: Dying drops your COG tags. Squadmates must carry them to a Supply Cache to revive you. Allied squads can also pick up your tags for instant revivals. A full squad wipe costs a precious Squad Life.
- Invasion Events: Massive bosses like Corpsers and Brumaks spawn across the map. These events impact all active squads, often blocking extraction routes or disabling Supply Caches.
- Poisons: Following major boss waves, Locust forces grow significantly stronger against your squad. Complete early side objectives to counteract this buff.
- Mission Modifiers: Higher difficulty levels introduce punishing modifiers, such as enemies regenerating health inside cover or exploding upon death.
- COG Resupplies: Supply Drops, Perk Caches, and Weapon Part Stockpiles spawn dynamically. Approach with caution, as opening them attracts aggressive Locust patrols.
- Extraction Window: The Raven chopper stays on-site for a strictly limited time. Missing this window means losing all collected Weapon Parts.
Horde Siege Playlists
Gears of War: E-Day offers an Onboarding mode to learn basics, alongside three distinct gameplay playlists. Each playlist features unique session lengths and tactical playstyles:

| Playlist | Structure | Approx. Length | Notes |
|---|---|---|---|
| Blitz | Complete 1–2 objectives | 15–20 minutes | Quickest option. Perfect for fast sessions or practicing class builds. |
| Siege | Complete multiple objectives across the map | 20–40 minutes | The standard Horde Siege experience centered around dynamic main objectives. |
| Horde | Defend one R.I.G. through 10 survival waves | 50–60 minutes | Longest playlist. Closest to traditional Gears Horde experiences. |
Note: Match times vary based on difficulty settings, squad execution, side tasks, and Invasion Events.
Primary Objectives and Secondary Objectives
Most operations center around R.I.G.s (Resonation Imaging Geographers). These vital scanners map Locust tunnels underneath Kalona. Five main R.I.G. objective types appear during operations:
| Mission | What You Need to Do |
|---|---|
| Secure | Clear all invading Locust forces from a designated zone. |
| Calibrate | Defend specific tactical zones while the R.I.G. completes calibration. |
| Repair | Scavenge scattered R.I.G. parts across the map to restore functionality. |
| Defend | Protect the active R.I.G. unit until its subterranean mapping completes. |
| Horde | Survive 10 waves of escalating Locust attacks centered around one R.I.G. |
Secondary Objectives
While completing main tasks, optional secondary objectives appear across the battlefield. These tasks provide vital resources and extra rewards.

- Defusing volatile Locust explosives.
- Eliminating High-Value Target (HVT) commanders.
- Recovering hidden COG intelligence packages.
- Transporting Power Cores to an allied squad’s R.I.G.
PRO-TIP: Keep track of Dynamic Events on your radar. Stay flexible, aid neighboring squads, and never let optional side tasks compromise your main extraction path.
Horde Siege Classes to Choose
Players can choose from four distinct combat classes. Each option features unique starting loadouts, passive bonuses, cooldown-based Tactical Gear, and a 30-level progression track:

| Class | Role / Playstyle | Tactical Gear | Passive |
|---|---|---|---|
| Assault | Mid-range all-rounder, excellent for holding down objectives. | Sonic Disruptor – Stuns groups of enemies. | Bonus weapon damage while positioned in cover. |
| Breacher | Aggressive close-range frontline fighter. | Adrenaline Injector – Heals health and reduces incoming damage. | Resistance to status effects and increased melee damage. |
| Marksman | Long-range precision specialist and overwatch. | Pulse Drone – Marks Locust targets for the entire squad. | Higher critical-hit damage multipliers. |
| Medic | Support class packing strong combat utility. | Stim Vaporizer – Heals and revives nearby allies across squads. | Faster natural health regeneration. |
PRO-TIP: There is no single mandatory class. The best composition depends on your chosen playlist, map layout, team synergy, and operational difficulty.
Horde Siege Difficulty Levels for Players
Horde Siege features four difficulty settings designed to scale with your character level. Tackling higher tiers without meeting recommended levels guarantees swift defeat:

| Difficulty Level | Recommended Class Level | Difficulty |
|---|---|---|
| Rookie | Class levels 0 – 10 | Beginner |
| Infantry | Class levels 10 – 20 | Challenging |
| Commander | Class levels 20 – 30 | Very difficult |
| Allfather | Max level classes only | Extreme |
Resources and Progression in Horde Siege
Resource management drives survival and long-term progression. Learn these fundamental economies before heading into operations:

| Resource / System | How It Works |
|---|---|
| Energy | Earned through kills and objective completions. Spend at Supply Caches for weapons, tactical gear, Squad Perks, and defensive turrets. |
| Weapon Parts | Used to unlock permanent Weapon Mods shared across all classes. Parts are permanently lost if your squad fails to extract. |
| Class Progression | Classes level up to Level 30, unlocking advanced loadout options, Armor Mods, Tactical Gear Mods, Weapon Mods, and base stat upgrades. |
| Squad Lives | A full squad wipe consumes one Squad Life. Exhausting all lives fails the mission, though you still receive partial match XP. |

Dominate the Locust hordes and accelerate your class leveling with these essential beginner tips and combat tricks:

- Play the Onboarding First: Master basic controls, objective types, the Energy economy, and extraction mechanics before entering public queues.
- Choose a Class That Fits Your Playstyle: Select Assault for flexible combat, Breacher for frontline engagements, Marksman for long-range precision, or Medic for team support.
