The weapons that came with Dec DLC dont have operative status ie. kills, headshots unlocks....
the maps from both DLC's aren't added to the "Traveler" o.s.
(as far as i can tell anyways)
The game....my two main issues are: shooting thru objects, i like this but dont like when a bullet travels thru 3 foot of soil/gravel then thru re-enforced concrete tubing.
And why can i take several bullets, shotgun blast but not a melee hit from a gun.
I also think that the DLC should have came with unique tag surrounds or images.
As for the game as a whole, it excellent, campaign was lil easy even on SS mode (beat the 4 end creatures without using a bullet) but were here for the MP so its all good.
