Automatic Door

An automatic door appears in Deathstar Checkpoint, Test Checkpoints, Slomo Test, Checkpoint 10 stage 2, Checkpoint 11 stage 4 (after the columns), (Checkpoint 11's boss in Mayhem Mode), Local Multiplayer, Smash Hit - Official Trailer, and Smash Hit VR in the Introductory Stage and Checkpoint 3 stage 2.

They do not need buttons to open, instead, they detect where the player is, and if close enough, the door will open. You can never crash into them.
