The blackwagon has a horn you can honk

[Snarplord XVI]

I didn't expect this level of realism, 10/10 horn mechanics

EDIT: People doubted it so press X on a controller or spacebar on K+M.

What is this sorcery? Where is it? I thought I'd covered every inch of that thing.

[H.P. Lovecrelftcius]

I don't believe this to be real, as I throughly touched and messed with every inch of the Blackwagon

[mega degrod]

I think we have been baited lol

[Tsukkei]

No! It's true! Press the spacebar as the blackwagon travels from place to place on the map. (seems to work better between longer distances...)

[VaultBoy]

Or hold X if you're using an X-Box controller.

[Snarplord XVI]

Yeah, press X or spacebar.

You're welcome.

Also, if you hold right trigger the screen will blur, which I initially thought made the transition faster. But actually it doesn't seem to achieve anything.
