Playing as a Prop might be fairly challenging. Your ultimate goal is to change into a Prop or object on the map and then hide from opponent players. You win that round if one Prop is still alive when time runs out or hunters have been killed themselves. Use an ‘E’ key when you are very close to a prop and a cursor is above it / in its area in order to transform into a prop. Be cautious not to get stuck when converting yourself into prop as you might end up with a wall or an additional prop.
Moving props in the gmod free could be used to your benefit to make an area tougher to search or to hide under anything else. To pick up a prop devoid of transforming into it press/hold crouch key (normally ‘Control’ or ‘Ctrl’) then press an ‘E’ key in order to pick the prop up. There are some things to note with that one being that you should be directly above a prop to pick it up as there should be a short distance between you and prop in order to pick it up. Then walking while carrying a prop is quite onerous as a prop bounces off resulting slowing you down, an ideal option is walking sideways or backward to avoid this. Thirdly, if, for any reason, a prop gets caught against a wall or any object in a game and you do not move it back out you’ll most likely drop it as you need to move.
