XCOM 2 Tactical Guide: Squad Builds, Class Tips, and Mission Strategy

XCOM 2 is a turn-based tactical game where every decision carries permanent consequences. Soldiers who die are gone forever. Missions failed remain failed. The strategic layer punishes mistakes for dozens of hours after they happen. This guide covers squad composition, class specialization, and mission tactics that keep your soldiers alive.

Squad Composition Basics

A standard six-soldier squad should include at least one of each: a Ranger for close-quarters damage, a Grenadier for guaranteed damage and cover destruction, a Specialist for healing and hacking, and a Sharpshooter for long-range elimination. The remaining two slots flex based on mission type.

Rangers split into Blademaster (melee) and Phantom (stealth) specializations. Phantom Rangers are more valuable: they keep concealment after the squad is revealed, providing permanent scouting. Blademasters deal devastating damage but put your soldier in danger with every attack.

Grenadiers choose between Demolition (cover destruction and area damage) and Heavy Gunner (suppression and high-volume fire). Demolition Grenadiers are essential: their grenades guarantee damage through cover that would cause shots to miss. Shredding armor with grenades makes every subsequent attack against that target more effective.

Specialists choose between Combat Medic and Combat Hacker. On Commander and Legend difficulty, Combat Medic is nearly mandatory. Revival Protocol brings unconscious soldiers back into the fight. Medical Protocol heals from range without using an action.

Sharpshooters choose between Sniper (long-range, high-damage) and Gunslinger (pistol specialist). Sniper with Squadsight can fire at any enemy visible to any squad member, meaning your Sharpshooter never needs to be near danger.

The Golden Rule: Never Activate Multiple Pods

Enemy groups (pods) are clusters of 2-4 aliens that activate when spotted. Activating one pod is manageable. Activating two simultaneously is often fatal. Always advance cautiously, keeping soldiers in blue-move range so they can still shoot. Never dash (yellow-move) unless you know the area ahead is clear.

Use a Phantom Ranger or Battle Scanner to reveal pods before your squad moves forward. Plan your engagement: which soldier shoots first, which enemy dies first, and where each soldier will be at the end of the turn. Kill or disable every activated enemy before moving forward to find the next pod.

Cover and Positioning

Full cover provides 40 defense. Half cover provides 20 defense. No cover provides 0 defense. Every soldier should end every turn in full cover unless they are in an elevated position or flanking an enemy.

Elevation provides +20 aim bonus and defense bonus. A Sharpshooter on a rooftop with Squadsight can cover the entire map. Always look for vertical positioning before committing to a fight.

Flanking removes all cover bonuses from the target and grants +40 aim. Flanking shots rarely miss. Position your Rangers and assault troops to flank while your Grenadier’s grenades destroy cover, creating flanking angles for the rest of the squad.

Mission Type Strategies

Timed missions (most guerrilla ops) force aggressive play. You cannot turtle and overwatchcrawl. Sprint a Phantom Ranger ahead to scout. Use grenades liberally to guarantee kills. Accept some risk to maintain pace — running out of time is worse than taking a wound.

VIP extraction requires a clear path to the extraction zone. Move toward the objective while engaging only pods directly blocking your path. Ignore pods you can avoid. Once you grab the VIP, sprint for extraction.

Retaliation missions require saving at least 6 of 13 civilians. Split your squad into two fire teams of three. Clear the map methodically, prioritizing Faceless (disguised aliens) that reveal when you approach civilians.

Facility missions have no timer and reward cautious play. Overwatchcrawl: advance one tile, set everyone on overwatch, advance another tile. Clear every pod deliberately.

Strategic Layer Tips

Build the Guerrilla Tactics School first for squad size upgrades. Build the Proving Ground second for experimental ammunition and grenades. Expand to new regions to increase your monthly income. Prioritize contacting the Resistance in regions with supply drops.

Manage your roster depth. Injuries take soldiers out for 5-25 days. If your A-team is all injured simultaneously, you need a competent B-team. Keep at least 8-10 soldiers leveled and equipped.
