The confirmed modes

Aliens: Fireteam Elite 2 supports its campaign in single-player and online co-op for two to four players, according to the Xbox Store. The official site separately confirms an updated Horde mode for squads seeking a replay-focused alternative.

Cross-platform co-op and cross-platform voice chat are confirmed for the four-player framework. Current product information does not provide a longer authoritative list of named modes, so check the live mode menu for any additions after launch.

What is known about Horde at launch

GamesRadar reports three Horde maps at launch and describes Horde as placing greater emphasis on intensity and squad strategy. The three-map count and that assessment are review findings, while the existence of the updated mode comes directly from the official site.

Published launch information does not specify exact wave rules, map names, objectives or rewards. Use the live mode screen for current rules and check later patch notes when balance changes.

How Horde changes squad priorities

Sustained pressure makes role coverage more important than a universal class ranking. T-Pose Games describes Machinist as area control, Medic as support, Marauder as heavy weapons, Hunter as weak-point pressure and Duelist as flexible damage, giving a squad distinct jobs to combine.

Build firing lanes around friendly-fire risk on higher difficulties. Explosives and wide-area weapons can become liabilities when teammates have nowhere safe to move, so damage output should be balanced with control, recovery and clear communication.

Progression and repeat-run planning

Weapon Traits and Augments unlock through weapon progression, while attachments change weapon statistics. Challenge Cards and consumables can also alter risk, rewards and tactics, making repeat runs useful for refining both the weapon and team plan.

Review the current patch before locking in a permanent Horde build. The official launch patch changed balance and fixed issues across perks, abilities, weapons, audio and platforms, so a loadout copied from an earlier version may no longer behave as described.
