Got into my head!
I have been a hard core Gamer since 1995. Out of the forty odd games I have played in depth this is my favorite!
The campaign is a delight if played on the highest difficulty.
The first impressions are - what is this awful map?
Then you realise that you have to make some decision's on what you spend your "prestige" on and that the map is artwork - you start to pay attention.
As you take the same force through each of the 20 odd missions - you both want them to survive and fight to gain XP.
What is special is you cannot afford a bad game in the campaign as this may affect you at a later date. ie a poor choice of purchase may mean down the track that you simply cannot win with gear you have - no matter how much XP it has.
The great online community give this game great deapth with maps and some excellant campaigns.
