"Playcraft is an innovative new multiplayer sandbox game creation experience that allows you to play and create a wide variety of game types – from action platforming adventures to physics based carnage-filled playgrounds.

In Playcraft players are able to create first or third person multiplayer games without the need for coding. It allows you to create a variety of game styles, including platformers, shooters or narrative adventures. It’s easy to use, with you able to switch between create and play modes at the touch of a button, and you able to easily share your creations with the rest of the community.

You can play solo if you like, but the whole create and play experience is better in multiplayer, with you able to work together to create your perfect games or just mess around and have some Garry’s Mod style physics based fun.
It’s an interesting new game building experience, where the process of creating the games can be as fun as the games themselves. »
