XCOM: Enemy Unknown Complete Pack

XCOM: Enemy Unknown Complete Pack brings together Firaxis Games' 2012 re-imagining of the 1994 strategy classic and everything built on top of it: the Enemy Within expansion, the Slingshot Pack and the Elite Soldier Pack. You take the commander's chair of XCOM, a secret paramilitary organization funded by a nervous Council of nations, and you are the last line between Earth and an alien invasion that grows bolder every month you fail to answer it. Between missions you run the base, the research and the politics; on the ground you move soldiers one turn at a time, knowing that a bad call costs you someone you named.

Running XCOM From the Ant Farm

The strategy layer is a cutaway view of your underground headquarters, and every excavated square matters. Laboratories speed research on recovered alien alloys, weapon fragments and live captives; Workshops cut Engineering costs; Satellite Uplinks let you watch more of the sky. Power is always short, and the choice between another Interceptor for a struggling continent and the Alien Containment unit you need for interrogations is rarely comfortable.

Sixteen Council nations watch your performance. Panic climbs in countries you cannot cover with satellites or fail to defend during abductions, and a nation that panics far enough withdraws its funding for good. Monthly Council reports grade you bluntly, and the campaign never lets you protect everyone, which is exactly what makes the choices bite.

Turn-Based Combat Where Losses Stick

Missions play out on maps that stretch from crashed UFOs in farmland to abduction sites in city streets, with squads of four to six soldiers moving in turns. Cover is everything: a soldier caught in the open by a Thin Man's poison or a Muton's plasma rifle rarely survives, while a Sniper on high ground with Squadsight can decide a fight from across the map.

Four soldier classes Rookies who survive their first mission are promoted into Assault, Heavy, Sniper or Support, each with a branching skill tree. Run and Gun, Suppression, Double Tap and Smoke Grenade are the tools that turn a rescue into a rout, and a Colonel is worth more than any weapon in the armory. Permanent death When a soldier falls, the name, nickname, kill count and every promotion goes with them. Firaxis leans into it with customizable names and appearances, so the squad you field in month six carries real history, and the Memorial Wall back at base fills up whether you like it or not. Escalating alien roster Sectoids and Floaters give way to Chryssalids that turn civilians into fresh horrors, Cyberdiscs that shrug off ballistic rounds, and psionic Ethereals that take control of your own troops. Interrogating captured aliens is the way to stay ahead of the research curve.

Enemy Within: Meld, MEC Troopers and EXALT

The expansion is not a separate campaign; it is woven through the whole game. A new alien resource called Meld appears on the battlefield in canisters set to self-destruct after a few turns, so grabbing it means breaking formation and moving aggressively when caution says otherwise. Spend it in two new facilities:

• The Genetics Lab lets you gene-mod individual soldiers with augmentations to the chest, brain, eyes, skin and legs, from Mimetic Skin that hides a soldier in cover to Secondary Heart that keeps them alive when they should be dead.
• The Cybernetics Lab converts a soldier into a MEC Trooper, a new class that pilots a Mechanized Exoskeletal Cybersuit with upgrades like a flamethrower, a grenade launcher and a Kinetic Strike Module that punches through walls and aliens alike.
• EXALT, a human paramilitary group working for the invaders, runs covert operations against you. Sending a lone operative to plant transmitters and then extracting them under fire is a new kind of mission, and tracking down EXALT's headquarters becomes a campaign within the campaign.
• Two new alien types, the Seeker and the Mechtoid, join the roster alongside over 40 new maps, new Foundry projects, new weapons and equipment, and new multiplayer units and abilities.

Slingshot, Elite Soldiers and Second Wave

The two content packs round out the campaign. The Slingshot Pack adds a chain of three linked Council missions alongside Zhang, a Triad operative with his own voice and story who joins your barracks as a Heavy; you divert an alien ship's course and take the fight to it in the skies over China. The Elite Soldier Pack adds a recruit modeled on the original X-COM: UFO Defense soldier, the Hyperion and Reaper armor kits, and color tints for every armor set, so a veteran squad can look the part.

Second Wave, a free update included in the base game, unlocks a set of optional modifiers when you start a new campaign: randomized rookie stats, Damage Roulette, Hidden Potential, and options that make funding and panic far less forgiving. Combined with Classic and Impossible difficulties and Ironman mode, which saves every decision permanently the moment you make it, the pack has years of replay in it.

One-on-One Multiplayer

The competitive mode is still running. You build a squad of humans, aliens or both within a points budget, then face another commander in a turn-based match where a single flanking shot swings the whole game. Enemy Within adds its units, abilities and maps to the pool, so a MEC Trooper can end up trading fire with a Mechtoid.

Whether you remember the 1994 original or you are meeting XCOM for the first time, this is the full campaign as Firaxis finished it. Pick up the Complete Pack, name your first squad after people you know, and find out how many of them make it to the Temple Ship.
