TheBridge going invis no potions

[nathanwastak3n]

I recently found people going invisible (without hitbox) in an instant without any potion. are they using hacks? is there a kit that lets them do that?

pretty sure its just spy kit and they have a limited time with it:
tier 1: 6secs of invis
tier 2: 12secs of invis
