"...the campaign is full of tense moments that are sure to keep you coming back for more." - IGN.com

"A wonderful and worthy strategy game with a layer of campy charm that makes the stone-faced seriousness of the game's characters all the more endearing. It's also remarkably accessible, thanks to a great interface that feels comfortable whether you're using a keyboard and mouse or have a controller in your hand." - Gamespot.com

The Perfect Strategy game

Pamq25k | May 1, 2015 | See all Pamq25k's reviews »

XCOM: Enemy Unknown is the best turn-based strategy game, offering a great AI, story, yet extremely challenging. It requires a lot of thought to manage panic all around the earth, not to mention that each and every decision you make might either save you or drag you to the bottom. Long story short: XCOM: Enemy Unknown is the game you need if you like thinking and challenges.


A reboot done right.

Shodex | March 31, 2015 | See all Shodex's reviews »

You'll be hard pressed to find a modern tactical strategy game on par with XCOM: Enemy Unknown. A streamlined reboot of the original classic that cuts out excess complication while leaving the crushing difficulty gleefully intact. In XCOM: Enemy Unknown you control a squad of elite soldiers against an invading alien menace. The combat takes place in turn based tactical battles where when your soldiers die, they die for good. It gets personal when a soldier you've named and becomes invested in gets killed in some heroic or not-so-heroic way. And most of the time it's your fault he got killed, not because XCOM was being unfair. If you're the kind of gamer who would rather a very challenging game that requires lots of thought, XCOM Enemy Unknown is a fantastic experience with a very high replay value.

I haven't really been playing much of the games of this genre, the one before this was probably Incubation demo. So I was going in this game pretty blindly with only a good word of mouth to guide me. And I wasn't disappointed. The game description tells you pretty much what you do in the game, so I' only going to tell my story. Being a bold gamer, I started with Normal difficulty, thinking it would be an easy first run-through. The game held my hand a bit longer than I would've wanted but it wasn't too drawn out. At first I got a squad of 4 to use, but not until the second mission. The first mission is a tutorial so it doesn't let you try anything fancy. The equipment is pretty basic at first, rifles for all and some grenades. Off I go, running from cover to cover, until I'm shot from the side. Soon enough, I'm starting to lose my men. I win eventually, but learned from my carelessness. Further, I started getting more and more cunning, careful and attached to my team. I'm not gonna lose another one. Not one. I save many times every mission, but never resort to beginning a mission anew. Getting better and better, I manage to beat the enemy on the battlefield but neglect the Council too much. I'm out of funding, game over. There was a whole other layer of tactics I didn't yet grasp, thinking how to build my base. Not enough satellites to cover the Councils nations was my mistake. But now I'm prepared. The next campaign will be in "Iron Man" mode...


The modern turn-based tactical game

Corax_E | March 17, 2015 | See all Corax_E's reviews »

Simply the best modern turn-based tactical game. While it's might be called simplistic compared to the original, the addition of cover mechanics and removal of action points creates a greater focus on tactics, flanking and takes out a lot of micromanagement. Also permadeath makes the missions very tense, not only because it means veterans are your most valuable resource but because you easily get very attached to your favorite soldiers. Unfortunately there is to few mission maps which tend to get a bit repetitive. The expansion Enemy Within does however mitigate this.


Looks like we're not alone in the Universe, Clarke.

X-COM Enemy Unknown marks the great return of a classic franchise. It's a turn-based strategy game with RPG elements. In fact, it has a lot in common with Valkyria Chronicles and feels more like a Tactical-RPG and a good one at that! The story is simple : Earth is getting invaded by aliens and the secret group X-COM is created to save the world. Simple, right? Each mission is battle you must win using the deep combat system that the developpers have crafted for thios game. Like in most Tactical RPG you can move each member of your team and attack but there is a twist : the background elements are not here only to be "pretty". You can climb on ladders, open doors, get through windows and even destroy walls! Imagine Valkyria Chronicles gameplay with all of that! The combats are fun, very fun. And in between you can search alien technology or upgrade your secret base and troops. The game is pretty challenging and has a lot of replay value (And online multiplayer!). Visually, X-COM uses a cartoonish style that looks really good. The soundtrack is nice but a bit classic for this genre. X-COM is a must have if you're a fan of Tactical RPG/Turn-based strategy games.
