To balance this advance, dedicating a soldier to one excludes him or her from the other. I made more than few foolish dashes to gather Meld that evolved my tactical approach from cautious advancement to frantic survival when suddenly ambushed.įor the first ten or so hours, Meld abounds and players are free to explore the potential of MECs and gene mods.

Harvesting Meld is as easy as positioning a troop next to a canister, but it adds another objective to each map, and a countdown timer for each maintains the tension that underpins the XCOM series. Both are governed by an alien resource called Meld, which now litters each map in glowing orange canisters.

The second is through stat-boosting genetic modifications. Each unlocks after the construction of cybernetics or genetics labs, respectively, enabling the manufacture of XCOM super soldiers to combat both Exalt and the Sectoids' breed of elite soldiers.The new soldier buffs come in two forms: the first is a hulking Mechanized Exoskeleton Cybersuit (MEC) with crushing weapon attachments. Thick with narrative irony, XCOM simultaneously develops two tracks of transhuman upgrades, the exact kind of alien-human integration that Exalt wants: MECs and gene mods. To further humanity's evolution, Exalt attempts to disrupt XCOM operations and promote the assimilation of alien technology into human biology. It's possible to play Enemy Within almost exactly like Enemy Unknown, but Enemy Within adds an optional quest line early on: Defend the XCOM nations and XCOM itself from a transhuman threat.

Think of the expansion as a lateral addition to a core game and mission list that remains unchanged. Its net effect is as captivating as its launch pad with new items, juiced-up soldiers, alien mechs, a new branching series of side quests, and 47 fresh battlegrounds ripe with opportunities for tactical excision.Įnemy Within's single-player campaign starts the same way as Enemy Unknown - bunkered in an underground military base at the brink of the end of the world, following the escalating war with the aliens to its climax. The expansion's potency is at worst intriguing and at best traumatic. Firaxis has elevated XCOM: Enemy Unknown's intensity through the bulkier risk-reward strategy system in its expansion, XCOM: Enemy Within.
