Dusk Golem
A 21st Century Rockefeller
Are you playing on PC? I've heard it's alot easier to time in that version because there's less input lag/delay on the button press.
I usually just disarm them when they're right after a checkpoint, otherwise it's just too risky.
Yup, am playing PC which might make a difference. There is a slight delay when you press and when the counter stops, but my mind must have gotten the timing down as 4/5 times I disarm it.
However, if there's not been a checkpoint for a while, I usually don't risk it.
