The idea behind this is to add a new tactical element into the game. MELD is contained in two canisters located somewhere on each Terror map, which must be retrieved within a certain number of turns before it self-destructs. No, that isn't the rejected sixth member of the Spice Girls, but a new currency used to genetically and cybernetically enhance your soldiers. A new tutorial mission immediately introduces you to MELD. Fortunately, Enemy Unknown is entirely geared toward making you want to do that, and it doesn't hesitate in letting you play with its new toys. This means you're playing through the same story a second time. There are downsides: financial management is now much more complicated, and the expansion is rather bottom-heavy, but like the genetic alterations to your soldiers, these are definitely sacrifices worth making.Īs an expansion Enemy Unknown is dissipated through the familiar XCOM campaign, as opposed to adding a single, separate chunk of game somewhere down the line. It adds new abilities, new equipment, new threats, new maps and new missions. It takes the base experience and augments it into something better, more novel and more substantial. How Enemy Within alters your soldiers is broadly speaking how it changes XCOM as a whole.
