Aliens Fireteam Elite 2 Campaign Coop: Play Together

The Aliens Fireteam Elite 2 campaign coop experience is built around a simple promise: grab two friends, lock and load, and survive the Xenomorph outbreak on LV-558 together. Cold Iron Studios designed all 15 missions across four biomes with four-player squads in mind, which means the pacing, enemy density, and resource drops all scale to reward teamwork. If you are weighing whether to run the aliens fireteam elite 2 campaign coop or go it alone, the answer depends on how much coordination you want and whether you trust AI squadmates to watch your back.

The stakes are higher this time because the sequel introduces a dedicated horde mode, six distinct USCM classes, and a 42-slot perk grid that fundamentally changes how you build your marine. That depth matters because the campaign throws mixed enemy types at you from the first mission, and the difficulty curve punishes players who ignore class synergy. Whether you are a veteran of the first game or a newcomer checking the Aliens: Fireteam Elite 2 Steam page for the first time, this guide breaks down exactly how the campaign coop structure works, what solo play looks like, and how to unlock everything the story has to offer.

Campaign Coop Structure: How the Fireteam Scales

The aliens fireteam elite 2 campaign coop supports up to four players at launch, a step up from the three-player cap in the original game. According to the official website, the fireteam consists of six USCM classes — Marauder, Duelist, Machinist, Hunter, Medic, and Specialist — and you can mix any combination of them across the 15 missions. That flexibility means you can run a balanced squad with one Medic, or go full aggression with four Marauders if your group has the aim to back it up.

Enemy health and spawn rates scale dynamically with your squad size, which is a critical detail for anyone planning a aliens fireteam elite 2 campaign solo run. The game does not simply add more Xenos; it adjusts the aggression AI, increases the frequency of special enemy spawns, and tightens the ammo economy. Community reports from the beta suggest that a full four-player squad sees roughly 30% more enemies per encounter than a solo player, but those enemies drop proportionally more credits and crafting materials.

Here is how the scaling breaks down across squad sizes: As you move from a full three-player fireteam down to two players or a solo operative, enemy health, damage output, and spawn rates adjust dynamically. Smaller squads face reduced enemy counts and weaker individual foes, while larger squads trigger more aggressive swarms and tougher elites to maintain challenge balance.

The ammo economy is the biggest differentiator between solo and coop play. Solo players get generous drops because the AI squadmates consume less ammunition, while a full squad must coordinate who carries the recon turret and who saves the heavy weapon rounds for elite enemies. If you are playing with randoms, establish a simple rule early: call out your reloads and mark ammo crates so nobody gets stranded mid-fight.

How AI Squadmates Compare to Human Players

If you cannot find a full group, the game fills empty slots with AI-controlled marines that follow your commands. These bots are competent but not exceptional — they will hold position, focus fire on marked targets, and use their class abilities on cooldown. However, they lack the situational awareness of human players, so you will need to babysit them during ambush sequences.

The practical takeaway is that AI squadmates work fine on Standard difficulty, but they struggle on Intense and above because they do not kite enemies or use environmental hazards. If you are attempting a aliens fireteam elite 2 campaign solo run on higher difficulties, consider the best solo build guide to compensate for the lack of human reaction time.

First Mission Guide: What to Expect on LV-558

The campaign opens on LV-558, a colony world that has gone dark after a distress signal cuts off mid-transmission. Your fireteam deploys to investigate, and within the first five minutes you will encounter the classic facehugger swarm that sets the tone for the entire run. The first mission serves as a tutorial for the three-weapon system: a primary weapon, an infinite-ammo sidearm, and a Signature weapon that has limited charges but deals massive damage.

For anyone looking for a aliens fireteam elite 2 first mission guide, the key is to conserve your Signature weapon charges for the first elite encounter. The mission ends with a Praetorian-class Xeno that spawns after you activate the evacuation beacon, and burning your heavy weapon early leaves you vulnerable. The game teaches you the cover-and-peek mechanic here, which becomes essential in later missions where Xenos flank from ceiling vents.

Here is a quick breakdown of the opening mission objectives: Your first task is to secure the evacuation point, then defend it against waves of Xenomorphs while a dropship arrives. You must also locate and activate three emergency beacons scattered across the facility, each guarded by a mini-boss, before finally holding the extraction zone for a timed countdown.

• Objective 1: Reach the colony admin building and restore auxiliary power

• Objective 2: Defend the generator room for 90 seconds against two waves

• Objective 3: Navigate the maintenance tunnels and avoid the facehugger nests

• Objective 4: Activate the evacuation beacon and survive the Praetorian ambush

The mission takes roughly 25 minutes on Standard difficulty with a full squad, and about 35 minutes solo because the AI bots move slower through scripted sequences.

Class Roles in the Opening Missions

Your class choice in the first mission determines how smoothly the early game goes. The Medic is the safest pick for new groups because the healing beacon ability offsets mistakes during the defense sequence. The Marauder excels at close-range clearing, which helps in the tight maintenance tunnels where shotguns shine. The Hunter provides long-range support that keeps facehuggers off your team before they close the distance.

The Specialist class is locked until you level five base classes to rank 4, so most players will not have access to it during their first campaign run. That is fine — the other five classes cover all the essential roles, and the 42-slot perk grid lets you customize your build to fill gaps in your squad composition.

Solo Campaign: Playing with Bots and Surviving Alone

The aliens fireteam elite 2 campaign solo experience is viable, but it requires a different approach than coop play. Without human teammates, you become the primary damage dealer, tank, and healer all at once. The AI squadmates handle basic combat, but they will not reposition to protect you during ambushes, and they waste their consumable items on minor threats.

According to community testing, the solo campaign takes about 12-14 hours to complete on Standard difficulty, compared to 8-10 hours with a coordinated squad. The extra time comes from slower enemy clearing and the need to backtrack for ammo more frequently. That said, solo play has one major advantage: you control every resource drop. In coop, teammates may grab the rare crafting materials you need for weapon upgrades; solo, everything is yours.

Here are the essential tips for solo play: Always keep a medkit and a turret deployable in your loadout, as they provide crucial self-sustain and firepower. Use the environment—choke points and elevated positions—to funnel enemies, and prioritize taking out spitters and bursters from range before they close in. Save your Signature weapon for elite or boss encounters.

• Maximize your infinite-ammo sidearm — upgrade it early because it is your fallback during ammo droughts

• Use the Medic class — the healing beacon compensates for the lack of human revives

• Position yourself at chokepoints — doorways and corridors funnel enemies into your line of fire

• Save consumables for boss fights — the final mission has multiple elite spawns that require burst damage

• Learn the patrol routes — Xenos follow set paths, and you can trigger them one group at a time

The AI squadmate revive mechanic is slower than human revives, so you must prioritize not going down in the first place. If you do get knocked, your bots will revive you after three seconds, but they will not clear nearby enemies first — you will likely get downed again immediately. For that reason, the stasis build that locks down enemies near your position is a popular choice for solo players, and you can see the full theorycrafting in the stasis build guide.

Difficulty Recommendations for Solo Runs

Not all difficulty levels are created equal when you are flying solo. The game offers Standard, Intense, Extreme, and Insane difficulties, and each one changes the enemy AI behavior significantly. On Standard, Xenos are slow and predictable, but on Intense they start flanking and using cover. Extreme adds faster movement and coordinated attacks, while Insane makes enemies nearly relentless, with increased damage and reduced reaction windows for dodging.

The jump from Intense to Extreme is the steepest because enemies gain armor-piercing attacks that ignore your defensive perks. Most solo players should stick to Intense as their ceiling, and only attempt Extreme after maxing out their weapon upgrades and perk grid. If you are unsure which difficulty suits your skill level, the difficulty guide breaks down the exact stat changes between each tier.

Final Mission and Campaign Ending: What Happens at the End

The aliens fireteam elite 2 final mission takes place in the Storr Boon's Mining Facility, a massive underground complex where the source of the outbreak is revealed. Without spoiling the story beats, the final mission is a three-phase boss fight that tests everything you learned across the previous 14 missions. Phase one involves clearing waves while activating coolant pumps, phase two is a chase sequence through collapsing tunnels, and phase three is the confrontation with the Queen-class Xeno that has been directing the swarm.

The aliens fireteam elite 2 campaign ending has multiple variations depending on your squad composition and the choices you make during the final mission. The game tracks your mission performance rating — based on accuracy, revives, and elite kills — and this rating determines which of the three ending cutscenes you see. A high rating unlocks the "Heroic" ending, while a low rating shows the "Survivor" ending.

The campaign unlockables extend beyond the ending variations. Completing all 15 missions on any difficulty unlocks the horde mode for that biome, and finishing on Intense or higher grants access to endgame weapon attachments that cannot be found in the standard loot pool. According to the official website, there are also hidden caches in each mission that reward cosmetic items for your marine, and these are repeatable through the mission select screen.

Post-Campaign Content and Replay Value

Once you finish the campaign, the game does not simply end. The mission select screen lets you replay any of the 15 missions with your upgraded gear, and the challenge cards system adds modifiers that increase difficulty in exchange for better rewards. These cards range from simple tweaks like "increased Xeno spawn rate" to wild changes like "all enemies are invisible until they attack."

The repeat mission system is designed for players who want to grind for the best gear, and you can read more about the replayable mission structure to plan your farming routes. The campaign is not a one-and-done experience — the perk grid and weapon attachment system give you dozens of hours of buildcrafting after the credits roll.

Mission Order and Progression Tips

The 15 missions are split across four biomes, and the order matters more than you might think. The game lets you replay earlier missions to grind levels, but the recommended mission order follows a specific power curve that assumes you are upgrading your weapons between each story beat. If you skip ahead, you will face enemies that outclass your gear.

The leveling curve is generous enough that you will hit the recommended level for each biome by simply playing through the story missions once. However, if you are struggling on a particular mission, the best mission order guide explains which side missions to grind for experience and which ones to skip.

Weapon Upgrade Priorities

Your credits are limited during the first playthrough, so you need to prioritize which weapons to upgrade. The three-weapon system means you carry a primary, a sidearm, and a Signature weapon, and each one serves a different purpose. The primary handles standard fodder, the sidearm is a backup for reload emergencies, and the Signature weapon—like a flamethrower or smartgun—is best reserved for heavy targets or crowd control. Upgrade the primary first for general reliability, then the Signature for boss fights.

• Primary weapon: Upgrade this first — it is your main damage output

• Sidearm: Upgrade second — it is your infinite-ammo fallback

• Signature weapon: Upgrade last — it has limited charges, so it matters less in sustained fights

The elemental ammo types — fire, cryo, electric, and piercing — add another layer to the upgrade system. Fire deals damage over time, cryo slows enemies, electric chains between targets, and piercing ignores armor. Each enemy type has a weakness, and the campaign encourages you to swap ammo types between missions based on the biome you are entering.
