XCOM: Enemy Unknown’s hits and misses (hands-on preview)

I’ll tell you what I know. We set down deep into the Nigerian interior on Council orders to get this thing. As we approached the downed alien craft, our assault team dashed into position using their run-and-gun tactic to double-time it to the UFO and eliminate a couple of little gray men crouching near the exterior walls.

Our support unit dropped smoke to cover our breach of the hull doors while our sniper watched over the entrance and our heavy-weapons expert laid down a suppressing fire just to be sure. The plan seemed fine.

We didn’t even see the strange creatures with surgically implanted jetpacks drop down behind our position and flank us. As they rained death from above onto the whole team, a ball of light raised itself up off the UFO floor and transformed into a bipedal monstrosity, which then turned its attention to the forward units and cut them down.

I’m lucky to be alive. … I had to fall back to the Skyranger and dust off from the crash-site investigation. I only hope this report can assist the next team as I recover in the infirmary. End log.

XCOM: Enemy Unknown, developer Firaxis’ update to the revered turn-based strategy classic X-Com: UFO Defense, is filled with stories like this. Ones that you write yourself as you send squad after squad into battle to hold off a planet-wide extraterrestrial invasion.

Those skirmishes are the heart of the series, so I set out to see what’s new and what’s different from the original. Publisher 2K Games provided me with a preview build of Enemy Unknown, and what follows are three new concepts that I think you’ll love and three old ideas you might miss from UFO Defense.


XCOM: Enemy Unknown

Mission variety

In a typical X-Com (or XCOM) campaign, you’re going to send dozens of soldiers to their deaths over the course of hundreds of tactical engagements. In other words, you’re going to spend a lot of time on the battlefield. And although UFO Defense features different pretenses for missions (like UFO crash-site investigations, alien base raids, and saving terrorized metropolises around the globe), they all boil down to a simple kill everything objective.

Enemy Unknown smartly adds actual goals for your military excursions. Every once in a while, The Council (nations that form the XCOM organization’s governing body and fund the operation) will pick up the red phone and ask you to send a strike team for a specialized task. That might include disarming a hidden bomb while simultaneously disabling nearby power nodes to buy yourself more time (you only have three turns!) or locating the survivor of an alien abduction and leading her to an extraction point.

These add welcome variety to what might otherwise cause even the most hardened commanders to burn out on the monotony of “kill, kill, kill.”

The two-action system

This change is likely to be contentious among long-time fans, but with it comes a step forward for the series: Enemy Unknown makes you commit to your decisions and then strongly enforces their consequences. This, if anything else, is the heart of a truly great game.

In UFO Defense, the flexibility of the Time Units system (which governed the actions soldiers could take in a turn) meant that you could make quite a few mistakes. You could send a soldier into a room, see a cadre of four or five invaders, fire off a snap shot, and run the hell out of there.

In Enemy Unknown, though, you can only take two actions per trooper per turn. And, unless you have unlocked a specific skill for the Heavy class, if you shoot as your first action, you forfeit the second. That means that in the scenario above, you’ve just committed your warrior to (hopefully) dodging or (more likely) soaking up volleys of alien weaponry for an entire round.

Reloading also costs a whole turn for your grunts whether they take the action first or second. And that inevitably makes the decision to slap in a new clip a gravely important one. Enemy Unknown’s system here — while not perfect as you’ll see on page two — keeps the tension incredibly high from start to finish.

XCOM: Enemy Unknown

Sticky-cover indicators

Cover in UFO Defense was anything you could stick a soldier behind, and that’s the case here again with Enemy Unknown. But back in the ‘90s, you could never be 100 percent sure that a wooden fence was actually going to block incoming plasma fire. The isometric view just didn’t provide the kind of visual assurance one expected.

Firaxis’ update places little shields over any cover near your “phone booth” cursor. A half-filled blue shield is partial cover while a full one is, well, full cover. A red shield means you’re open to fire, and a gold shield means the enemy has just flanked your position. Time to move!

This is invaluable information, and I’m very pleased to see it presented so clearly to the player.


While Firaxis does add to X-Com’s classic gameplay in many ways, its new take on tactical battles also makes quite a few less noticeable changes that could have an otherwise large impact. Read on to page two to find out what’s missing.
