For all the bugs and negatives this game has, I still got plenty of enjoyment out of it. Actually, I have just finished the game for the second time. Never before this did I feel the urge to immediately replay a game after completing it for the first time.
On the first go, I didn't kill a single person. Okay, I was forced make an exception in the last mission, but other than that, I just beat those unconscious who were really in the way.
For the second time I decided to kill everyone the first chance I got. Unarmed civilians, friends, little children? DIE!
Granted I'm a bit disappointed now that the two polar opposites played out almost exactly the same, other than having less people alive, including those who would have been part of a future mission, thus I had less to do than the first time around.
I was hoping someone would at least comment on my massacring every innocent civilian, or maybe for some new faces to substitute those that I disposed of... Most of the more important characters' deaths got a mention though.
Anyway, it's still refreshing to be able to eventually kill each and every character in a first person shooter, which Invisible War most certainly is. I wonder what makes some reviewers insist DXIW is not a shooter, while they are happy to label the Elite Force games or NOLF1-2 as a FPS.
So my point is simply that you should give this game a chance. Maybe wait for some more patches and the price to go down.. You might even like it. A lot.
