Fortnite developer Epic has announced the temporary closure of the games sandbox mode, Playground, to take place on July 12.Allowing players to test out the games controls and building mechanics in a less pressured environment, the new 4-player Playground mode has already fostered a budding crafting community, and offers a more casual experience than the games hyper-competitive Battle Royale mode in which 100 players battle to be the last one standing.Its not all bad news, however, as Epic promises the mode will be back soon with a host of new improvements.Ch-ch-changesEpic took to Reddit to run through some of the expected changes, including the ability to select 1v1 or 2v2 teams, and see markers for teammates on the in-game map.Players will also be able to edit other players structures while a new aim assist should help newcomers getting to grips with the games controls.The current top-voted comment on the Reddit thread calls for an additional keep loot option, so that players can carry their spoils across from one session to another.Theres no firm date for Playgrounds return, but given that the mode's only been online for a few days so far, we're hoping we won't have to wait too long
