KF2 v1007 Siren basic info and dodges
Early Access Killing Floor 2 v1007 Siren mechanics and info.
As an added FYI - currently the scream pull has been disabled for v1007. Her screams do have the ability to pull you in closer but for some serious rubberbanding issue it has been disabled and is currently being looked into.
A video showing off the Sirens in KF2, how their screams work and an interesting dodge strat that expands on anything I've ever seen in KF1.
