Did you guys also saw footsteps in icebox?

So yesterday we played a 5man unranked with friends. At the very start of the match, one friend and I (other two were afk and last one is blind cause boomer) saw what i can only described as footsteps in the snow. Exactly like an invisible man walking in the snow (from mid to left side of spawn on CT side).

Footsteps were blue'ish back'ish with some effected that made me think of omen (blue'ish smoke around them).

I had no clue at the time, but now that you guys mention new invisible agent, this all makes sense.

Its probably safe to assume that the new agent is japanese and have some way of going invisible. Main color is probably blue (darker blue then Sova).
