I'm giving this DLC 3 points because that's what it is. It's a DLC not a new game.
When you take an existing game and you add, weapons, enemies, skills, etc. You call that a DLC and price it accordingly. Shame for trying to sell this as a new game.
That aside, if you enjoyed X-Com enemy unknown then you'll feel right at home. Same exact game with some new additions.
The game froze on me at various points of gameplay. Making it really annoying since it would usually happen during a mission and force to restart the game, load the savegame, and start the mission all over.
Note. This has never happened with the original X-com Enemy Unknown, even after several play throughs.
