First, I must unfortunately give my speakers right, I had the same problem (Speil could not be installed). Have I therefore have to draw an ISO to install the game.
To play but my drive enough then probably.
For game itself.
-About The pathfinding of vehicles we need not even talk because you 8Jahren has done nothing, but every fan lives halt it.
-The Game is more of a mission pack, or rather a mini mission pack, but already very detailed.
-Although I have a very strong computer, the game when many vehicles running (especially helicopters) in use are no longer beautiful liquid, more like gelatin.
Conclusion:
Who is a fan and whom 2012 has already fallen, the game can definitely get. Correct it worth it will probably have for the people who neither EM2012 still EM13.
What I miss personally is the old charm of the game (Em2,3 & 4). This doomsday story is not really my thing, and the control was messed up to my taste than the developers have tried to make the game for the masses affable.
