I didn't find much violence here. When you shoot a plane down, all you see is smoke trailing off the plane, and a small fireball, no pain or blood evident.
The worst language I heard was minor shouting, with no swearing involved.
H.A.W.X 2 is not a mature game. Its an arcade type flying game, with lots of shooting down planes. In the violence sense, You shoot down planes and crash but there is no blood or sign of pain. They just simply drop out of the sky in a huge explosion. There is some cussing but its nothing really major. Overall its good for younger audiences as well as adults.
Its a good game, another great WWIII instalment in the tom Clancy series...you get to blow stuff up! Some of the characters swear from time to time (sh#t pi#sed off) and in cut scenes you hear about attacks and that kind of stuff, there is also warzone footage which looks like it is from a game for older people in some cut scenes (only a few seconds). (Although, it is possible to skip through the before level cut scenes)
In a level you see a spy/mercenary "take out" two guards yet no blood is shown.(zoomed in top down view in night vision) with In the first level a bad guy shoots an RPG at a helicopter. This is an awesome game and the satellite footage graphics are amazing! and the dogfight mechanics are really cool!!! (although they take some getting used to :D)
