Valve's new hero shooter Deadlock exceeds 150,000 concurrents despite still being invite-only as a new Portal 2 reference appears in-game

Valve's Deadlock has soared past 160,000 concurrent players, and now it's having a bit of fun by seemingly throwing a Portal reference into the mix.

The past weekend saw huge traffic for Deadlock, Valve's in-development hero shooter that was previously the worst-kept secret in the games industry. According to SteamDB, Deadlock achieved a staggering peak concurrent player count on Steam of 164,855 players, which is just wild numbers for a game that isn't even out yet and still requires manual invitations from existing players for newcomers to participate in.

At the same time, the new hero shooter is seemingly having a little fun with its development heritage. As seen below, Deadlock's teleporters, which spirit its heroes around the map in the blink of an eye, now apparently reference the main title card for Portal 2 - which is pretty thematically appropriate, even if it is a little on the nose for references. 

The teleporters now have a logo on them that seem to reference the Portal 2 logo
