Carry On Together two player carrying tips start with matching your partner: both players grab the same piece, lift together, and turn it with the mouse wheel while you keep it level.
Carry On Together two player carrying tips: the lift
- Check the crew icon on the job sheet before anybody reaches for the piece. A two-people icon means it is a team lift, and a one-hand icon means you are wasting a second player.
- Both players grab the same item at the same moment. The piece is a physical object shared between you, not two separate copies, so it has to start moving together.
- Move in short bursts and keep the piece level. The physics will happily throw a tilted sofa out of your hands.
- Turn the piece with the mouse wheel as you go, so the angle is set before you reach the doorway rather than in front of it.
- Release together. If the piece will not fit where it is, use Drop - Hold to Throw and get it out of the way.

Carry On Together rotate objects: how the mouse wheel works
While you are holding something, the control list adds Mouse Wheel - Rotate Item. That wheel is the only way to turn a piece in your hands, and it is what makes a sofa fit through a door that it does not fit through lengthwise.
Rotating is a co-op-only action right now. Objects can only be rotated while several players are holding them, which is exactly why the rotate control does not appear in a single-player session. If you are playing alone and want to angle a piece, the options are to turn the character around and to walk it in from a different direction.
A sofa can still be thrown by the physics even while two people are holding it, so keep the item level and keep the grip steady while turning it.
When the piece drifts and the two of you stop agreeing about where it is, ping it so the whole crew goes to the same object.
Why a two-player carry breaks
Tight corridors, slippery stairs and that one friend who lets go at the worst possible moment are what break a move. The developers describe the intended way to work as stretching out your arms, syncing up with your teammates and lifting together.
Carrying has been reworked several times during the demo, and the fixes all point the same way: an earlier grip that broke during a two-player carry, items clipping into the carrier's body so the hands floated off the surface, and solo-carried items catching on the ground or on road seams. A newer build also fixed items suddenly launching and jittering mid-carry, so if a lift feels like it is fighting you, check that your game is up to date.
If the carry keeps breaking because the piece is simply too big for the route, that is a route problem rather than a grip problem — moving furniture through tight spaces covers the checks that make the corridor work.
