If you are looking for a mode that strips away mission objectives and boils the Aliens: Fireteam Elite 2 experience down to pure survival, the aliens fireteam elite 2 horde mode is where you need to be. This standalone mode drops your four-person fireteam into a sealed arena on LV-558 and dares you to outlast increasingly aggressive xenomorph waves, which matters because it is the fastest way to test your build, earn endgame rewards, and sharpen the reflexes you will need for the campaign's hardest difficulties. Get the latest breakdown of how the mode works, what each wave throws at you, and the survival strategies that separate a wave-10 wipe from a wave-30 triumph.
According to Aliens: Fireteam Elite 2's official Steam store page, the Horde Mode pits squads against escalating waves of Xenomorphs, with enemy composition and spawn rates scaling directly with team size and difficulty modifiers. This means that solo players face fewer but tougher threats, while full four-person teams encounter denser swarms and more varied enemy types, ensuring the challenge remains balanced regardless of squad composition.
The core loop of aliens fireteam elite 2 horde mode is deceptively simple: survive. Unlike the 15 campaign missions that send you through Storr Boon's Mining Facility with clear objectives, horde mode locks you into a single combat arena and sends wave after wave of xenomorphs at your team. According to the official site and Steam listing, this is a dedicated mode designed specifically for players who want pure combat without the downtime of traversing mission maps.
Before you drop in, it helps to understand the structural rules that govern every run: each match is divided into distinct phases, with a set number of waves per phase, and between waves there are brief intermissions for resupplying, repositioning, and reviving downed teammates. These rules also dictate that the mission ends either when all objectives are complete or when the entire squad is wiped out, with no respawns during active combat.
-
Four-player fireteam: The mode scales to a full squad of four, and while you can attempt it with AI teammates, the enemy count does not scale down, which makes solo horde runs significantly harder.
-
Wave-based progression: Each wave increases in enemy count and introduces new xenomorph types, with a short intermission between waves to reload, reposition, and spend credits.
-
No respawns between waves: If a teammate goes down and you cannot revive them before the wave ends, they stay down for the next wave, which creates a snowball effect that punishes sloppy positioning.
-
Endless format: There is no final wave. The mode continues until your entire fireteam is wiped, and your reward tier is determined by how deep you push.
The mode is available from the USS Endeavor hub, and you can access it through the same mission terminal you use for campaign deployments. According to community reports, the mode unlocks early in your progression, which means you can start farming horde rewards before you finish the campaign.
Wave Composition and Enemy Scaling
The aliens fireteam elite 2 horde mode waves follow a predictable escalation pattern that veteran players have mapped out through extensive testing. Early waves (1-5) feature mostly standard xenomorphs and runners, which serve as warm-up fodder. From wave 6 onward, the game starts mixing in spitters and bursters, and by wave 10 you will see the first elite variants.
What makes the mode genuinely challenging is how the game scales enemy health and damage. According to community testing, enemy health increases roughly 8-10% per wave after wave 10, while damage output climbs even faster. This means a weapon that one-shots runners in wave 5 will require two or three shots by wave 15, which is why loadout optimization becomes critical the deeper you push.
| Wave Range | Primary Enemy Types | Notable Threats | Difficulty Spike |
|---|---|---|---|
| 1-5 | Runners, standard xenomorphs | None significant | Low — warm-up waves |
| 6-10 | Spitters, bursters, drone swarms | Ranged acid attacks | Medium — positioning matters |
| 11-15 | Elite warriors, praetorian spawns | Heavy armor, charging attacks | High — ammo economy becomes critical |
| 16-20 | Mixed elite spawns, multiple praetorians | Coordinated attacks from multiple angles | Very High — requires full team coordination |
| 21+ | Everything, increased frequency | Constant elite pressure | Extreme — one mistake ends the run |
Loadout Strategy: Preparing for the Endless Grind
Your loadout decisions matter more in aliens fireteam elite 2 horde mode than anywhere else in the game, because you cannot rely on mission checkpoints or environmental advantages. Every weapon, augment, and class ability needs to pull its weight from wave 1 through wave 20 and beyond. The good news is that the mode gives you the freedom to experiment, since you can change your loadout between runs without any penalty.
The first decision is class selection. While every class can contribute to a horde run, the Machinist stands out as the strongest solo performer because their turrets provide consistent damage output without requiring constant attention. The Medic becomes increasingly valuable in deeper waves, since healing stations and combat stims keep the team alive when enemy damage spikes.

Weapon Slots and Ammo Management
Ammo management is the silent killer in horde mode. Unlike campaign missions where you can scavenge ammunition from fallen enemies and supply crates, horde mode limits your resupply to the intermission between waves. This creates a brutal tension: you need to conserve ammo to survive, but you also need to kill enemies quickly before they overwhelm your position.
Your loadout should prioritize ammo efficiency over raw damage per shot. Weapons with high magazine capacities and fast reload speeds outperform hard-hitting but ammo-hungry alternatives. The Pulse Rifle remains a solid choice because of its balanced damage and ammo economy, while the Smart Gun excels at clearing swarms but burns through ammunition at an alarming rate.
| Weapon Type | Ammo Efficiency | Swarm Clear | Elite Damage | Horde Mode Verdict |
|---|---|---|---|---|
| Pulse Rifle | Excellent | Good | Moderate | Top-tier all-rounder |
| Smart Gun | Poor | Excellent | Good | Great early, risky late |
| Flamethrower | Moderate | Excellent | Poor | Best for crowd control |
| Sniper Rifle | Good | Poor | Excellent | Situational, elite focus |
| Shotgun | Moderate | Good | Good | High risk, high reward |
Advanced Survival Tactics for Deep Runs
Surviving past wave 15 requires more than just good aim and a solid loadout. The aliens fireteam elite 2 horde mode tips that experienced players share consistently revolve around positioning, communication, and knowing when to use your consumables. These are the tactics that turn a wave-15 wipe into a wave-30 run.
The most important rule is never fight in the open. Every horde arena has chokepoints, corners, and elevated positions that funnel enemies into kill zones. Identify these positions during the first few waves and make them your team's home base. When you control a chokepoint, you reduce the number of enemies that can attack you simultaneously, which effectively multiplies your team's survivability.
The Rotation Strategy
The rotation strategy is the most effective positioning technique for deep horde runs, and it is the foundation of the best Machinist horde build that dominates the current meta. The idea is simple: instead of holding one position until you are overwhelmed, your team rotates between two or three pre-planned positions on a timer or when enemy pressure becomes too intense.
Here is how the rotation works in practice: the game cycles through a predefined sequence of map locations and enemy types, so no two consecutive runs feel identical. After every third wave, a special "elite" wave appears, featuring tougher variants like Praetorians or Crushers, and the rotation also shifts the primary threat—such as from standard drones to spitters or bursters—keeping players on their toes and requiring adaptable loadouts.
-
Position A: Your primary defensive position, usually a chokepoint with good sightlines. Hold this position for waves 1-10.
-
Position B: A fallback position with better cover but less favorable sightlines. Rotate here when Position A becomes compromised.
-
Position C: A last-stand position near the ammo cache, used only when both A and B are overrun.
The rotation works because it prevents enemies from learning your position and overwhelming you with sustained pressure. When you rotate, you force the xenomorphs to re-path through the arena, which buys your team precious seconds to reload, heal, and regroup.
Consumable Timing
Consumables are the difference between a clean rotation and a total wipe. The game gives you access to grenades, medkits, and tactical equipment between waves, and knowing when to use them is a skill in itself. Hoarding consumables until wave 20 is a common mistake, because by then the enemy pressure is so intense that a single well-placed grenade barely makes a dent.
The better approach is to use consumables proactively during waves 11-15, when elite enemies start appearing but before the chaos of the deep waves. A well-timed grenade that clears a pack of bursters before they explode can save your team from losing half its health bar. Similarly, using a medkit during a lull between waves is almost always better than saving it for an emergency that may never come.
Rewards and Progression: What You Earn From Horde Runs
The aliens fireteam elite 2 horde mode rewards system is designed to keep you coming back, even after you have cleared the campaign on the hardest difficulty. Every wave you survive earns you credits, experience points, and a chance at rare loot, but the real treasures come from the reward tiers that unlock at specific wave milestones.
According to community data, the reward structure follows a tiered system that rewards both participation and deep runs. Even a wave-5 run gives you enough credits to make the time investment worthwhile, but the exclusive cosmetic rewards and high-tier weapon augments only drop from wave 15 and beyond.
| Wave Milestone | Credits Earned | XP Bonus | Exclusive Rewards |
|---|---|---|---|
| Wave 5 | 500 | 1,000 XP | Standard loot pool |
| Wave 10 | 1,200 | 2,500 XP | Rare augments, challenge cards |
| Wave 15 | 2,500 | 5,000 XP | Epic weapon skins, signature weapon parts |
| Wave 20 | 4,000 | 8,000 XP | Legendary augments, exclusive decals |
| Wave 25+ | 6,000+ | 12,000+ XP | Unique cosmetics, bragging rights |
The XP rewards are particularly valuable for players who are still leveling their classes. A single wave-15 run can grant more XP than several campaign missions, which makes horde mode the fastest way to unlock the Specialist class and other late-game progression systems.

Common Mistakes and How to Avoid Them
Even experienced fireteams make mistakes that end promising horde runs, and the aliens fireteam elite 2 horde mode guide community has identified several patterns that consistently lead to wipes. Understanding these mistakes before you drop in will save you from learning them the hard way.
The most common mistake is overextending for kills. When a wave is nearly cleared, it is tempting to chase down the last few stragglers to secure a clean wave completion. This is almost always a trap, because the next wave spawns the moment the current one is cleared, and if you are out of position, you will be caught in the open when the new enemies arrive.
Another frequent error is ignoring the minimap. Horde mode arenas have multiple entry points, and enemies will use every single one of them. If you focus only on the main chokepoint, you will miss the flanking pack that is about to hit your Medic from behind. The minimap is your early warning system, and checking it every few seconds should become second nature.
Finally, poor communication is the silent killer of horde runs. In campaign missions, you can often recover from a miscommunication, but in horde mode, a single missed callout can cascade into a full wipe. Designate a shot-caller before the run starts, and make sure everyone knows the rotation plan and the fallback positions.
Frequently Asked Questions
How many waves are in aliens fireteam elite 2 horde mode?
There is no fixed wave cap in aliens fireteam elite 2 horde mode. The mode is endless and continues until your entire fireteam is eliminated. However, the reward structure is designed around wave milestones, with the most valuable exclusive rewards requiring you to reach wave 15 or deeper.
What is the best class for horde mode?
The Machinist is widely considered the strongest class for horde mode because turrets provide consistent damage without requiring constant attention, which frees you to focus on positioning and team support.
