Should of been more, semi auto is for noobs who cant snipe and get one shot kills so they need to spray their Barrett or M21.
total bollocks m8
semi-auto works a treat, you still get 1 hit kills and when they have painkiller, you get a hitmarker, or you just plain miss the target, the semi's still get you the kill.
semi's in the case of the barret, are equally as accurate, same damage, plus they have a much faster fire rate and larger clip size.
the reason for choosing bolt actions in real life, is they have more accuracy and longer range, on mw2 all the snipers have 100% accuracy and the barret has the same damage and range.
there is not 1 reason why anyone should be using the intervention over the barret, statistically the barret is superior in every way.
the only reason people use them is because they are bolt-action fanboys, wannabe pro's or they have been mislead by incorrect in game stats.
its just personal preference, if you line them up and actually compare with your brain and the factual statistics the barret is hugely superior in game. saying that, you can still do well with either, but if the argument is the intervention is better then your wrong.
i can guarantee me and my barret or me and my M21 beat you and your intervention on every map and every mode
