6DOF shooters have a tradition of including an optional auto-level or auto-roll system, and SL0 is not going to differ in that regard.
Being free to move on all axes can take a bit of getting used to, and without help, new players might find themselves panicking about being at 58.392 degrees to the ground and not knowing what to do about it. So whenever the ship is off-axis, autolevelling mode gradually rolls toward zero to give them one less thing to think about.
Here’s a scientific diagram to illustrate.
It’s particularly helpful for players using controllers, since with limited sticks/buttons it challenging to find an optimal layout. We’ve got a number of layouts for the player to choose from, which do allow all movements, but it’s not as simple and a mouse/keyboard setup.
Obviously, it’s entirely optional - we expect that most players won’t need it for long, and you have more control without it. But hopefully it makes SL0 a little more inviting to the 6DOF newbie!
P.S. But for the love of god don’t use autolevelling in VR. BLUUUUUHHHHRRRRRGH
