Horde Mode
Aliens: Fireteam Elite 2 horde mode — endless Xenomorph waves at launch, how waves work, the Specialist endgame loadout and the strategies that keep your four-marine squad alive.
Introduction
Horde mode is Aliens: Fireteam Elite 2's dedicated endless-wave game mode at launch. Your four-marine squad holds a position while escalating Xenomorph waves crash against your defenses, mixing every enemy type into a relentless survival test. It is the mode where the Specialist class truly shines, because its customizable ability mix can be tailored to endless-wave survival, and it is where elemental ammo, Signature weapons and ammo management matter most. Horde mode has its own reward table, challenges and leaderboards, making it the natural long-term endgame for players who want to keep fighting after the campaign ends, and every wave you survive teaches the squad something new about positioning and teamwork.
Horde Wave Survival Reference
| Wave Phase | Enemy Mix | Threat | Survival Focus |
|---|---|---|---|
| Opening waves | Drone swarms and light Xenomorphs | Low | Learn the arena and set up turret positions |
| Mid waves | Strikers, Exploders and mixed packs | Medium | Rotate elemental ammo and protect the Machinist turret |
| Escalation waves | Sirens, Wardens and Crusher pressure | High | Kill Sirens first; coordinated focus fire on Wardens |
| Endless tail | Full roster including Harbingers and Bulwarks | Critical | Survive the never-ending conflict and chase rewards |

Core Mechanics
Horde mode escalates in phases. Early waves are simple Drone swarms that teach you the arena and let the Machinist establish a Sentry Turret anchor. Mid waves introduce fast Strikers and suicide Exploders, forcing you to manage ammo and keep your formation tight. Escalation waves bring Sirens and Wardens, which break formations and call reinforcements, so the squad must coordinate focus fire and call out targets. The endless tail mixes the full enemy roster, and only teams that manage ammo, cooldowns and positioning can survive indefinitely. A Specialist loadout built for horde — turret support, healing and high sustained damage — is the strongest endgame approach.
Advantages
Horde mode is the ultimate test of everything the game teaches, and its endless structure gives you a clear endgame goal with leaderboards to chase. The mode rewards team composition: a Medic for healing, a Machinist for the turret anchor, and Marauder or Duelist damage dealers create a squad that can hold a lane indefinitely. Its own reward table and challenges give you a reason to keep improving even after the campaign is complete, and every wave survived is a small milestone that pushes your squad to refine its loadouts and tactics. Pushing your wave record requires the whole squad to improve together, which these guides help you do with clear, repeatable strategies.
Challenges
Horde mode is unforgiving — a single missed Siren or a burnt-out turret can cascade into a wipe, so mistakes are punished harder than in the campaign. Ammo and fuel are limited, so Signature weapons must be saved for the right moment rather than used freely. Endless waves get progressively harder and eventually outpace even the best team, so there is always a ceiling; the fun is how far you can push before it, and pre-launch wave details come from verified coverage and may change at launch. Horde strategy guides will be refined with wave data gathered from live play after launch.

Quick Tips
Set up before the wave announcement — turrets, ammo boxes and positioning all matter in the ten seconds between waves, and a prepared squad survives the endless tail far longer than one that scrambles after the first Siren call signals the swarm. Small improvements between waves compound into much longer survival over a full run.
Never chase a fleeing Exploder into the swarm; break line of sight behind cover and let it detonate harmlessly, then re-engage the rest of the wave. Chasing it pulls you out of formation and into the exact ambush it is trying to create. Small improvements between waves compound into much longer survival over a full run.
Track your team's Signature weapon cooldowns and save them for Sirens and Wardens — the difference between a clean wave and a wipe is usually one well-timed heavy hit, so communicate who is holding what for the next escalation before it starts. Small improvements between waves compound into much longer survival over a full run.
