Takedown is borderline usable if you play on PC and take a breather between shots...but even then, the recoil is so absurd that you might as well use Grendel, Scar or DSG instead.
In most sensible shooters the first bullet gives the least recoil and subsequent bullets continue to increase it (to encourage burst firing), but in Crysis 3 the first bullet has like a 3x recoil multiplier for assault rifles. Meanwhile semi-auto guns like Takedown and DSG just have an insane jump between shots
that is impossible to compensate for, it's not a "skill" thing, it's just stupid.
All those Crysis 2 players who said recoil was too easy in C2 and they were far happier with C3 recoil, screw you. "Realistic" recoil has no place in a freaking arena shooter. I suppose the same people are happy that shooting while jumping/strafing decreases accuracy...probably because they're too scared of what will happen when a skilled player starts headshotting people while jumping through the air.
Anyway the game got it's last patch a few months ago, play with what you got.
Also stay away from Warface, Crytek's 3th (?) attempt at a multiplayer shooter.
REAL multiplayer shooters BF4, Destiny and Titanfall are coming...next 2 years are going to be Crytek-free for me
