I read that you need BOTH ARMA 2 and ARMA 2: Operation Arrowhead to play this. I only have ARMA 2 though
I want to play this mod so bad...damn.
Operation Arrowhead is a different game to AMRA II, not an add on pack. Which reminds me of two things: I keep meaning to to that add on pack that adds Euro forces to Operation Arrowhead, and you can download most of AMRA II for free (and legal) from Bohemia Interative's website I do believe. I think it misses out the story levels or something though.
Bought BF3 from a second hand store for £18. Now apparently I need to pay EA £8 for the privilege of playing an online game online... Then to get that Back to Karkand pack I should pay another £18, or I could pay £40 to get some premium version or something. EA are really trying to suck money out of this game. Don't think they're going to get much out of me, didn't really love the gameplay when I did the single player bit - surprised EA didn't try to charge me for that.
A health bar or some equivalent should be mandatory for all games where it is applicable.
