This extension makes the already grandiose main game even better!

XCOM - Enemey Within is really a very classic extension that fits perfectly into the classic storyline of the game.
I have already invested in the main game, many, many hours of play, XCOM is a game that simply has a incredibly high replayability. Through Enemy Within this is again gone up.
I have now alluded Enemy Within about 20 hours and explain now just a few things that have stuck with me most:

+ New Class MEC: Very sensible addition to the squad, with the flamethrower can be enemies in a cone in front of him radius beautifully by roasting. Especially good if a few Chrysaliden want a back to my body. (Flamethrower is just one of many options on how to equip its soldiers MEC)

+ Attack the X-Com base: I have loved you once already with the classic "UFO Enemy Unknown": The attacks of the aliens on the XCOM base! An absolute creeps experience when you realize at once what was going on and the aliens storming into the base. Very well-crafted mission.

+ Much larger map diversity: UFOs landing and crash into populated areas, the missions have become more varied considerably.

+ Gene modification of soldiers: Here you can really let off steam and to increase its troop sense, the more one adapts to his soldiers - "zoom breed" a new soldier will cost a lot of time and resources.

I could now call many more points, but I'll keep something shorter:
This extension has vollstens convinced me! The music and the whole atmosphere in the game is simply consistent and just fits! And with a price below 30, this expansion has definitely deserves all 5 stars!

Who has liked Enemy Unknown will love Enemy Within!

Additional:

I can 1 star rating because of "story is not continued" to understand his eyes. Had to read the info text to Enemy Within, you know that it never was talking about. The action of the main game is extended implemented absolutely useful and good in many respects. (Hence the term extension or add-on)
