IGT is 50:20

tried to get sub 50 but... -Messed up to kill worms in Episode.4 (Chap.1)

-Tried to activate Berserker glitch to kill Reaper but failed so I lost about 30 seconds :(

I killed Hyde Bohr by using handgun(s449) and Anti-wad bullets it can fill liberation guage so quickly(safety strategy)

Anyway I found a way to kill Hyde Bohr very quick by use hand gun(T250 21.3cm) but I think it's depend on your luck and easy to mess up (Video link :)
