Double check you're going about it the right way. First subscribe to one of these items...

https://steamhost.cn/steamcommunity_com/workshop/browse/?appid=410900&browsesort=trend&section=readytouseitems&actualsort=trend&p=1&days=-1

If you want to play the map in Multiplayer, host a game, click "map", then click the "player" tab and you should see the map you subscribed to. Same works for mods.

If you want to play the map in Skirmish, make sure the map you've subscribed to has the "Skirmish" tag. You can use the filters in the Workshop on the right hand side to show only Skirmish maps, or you can see the tag a map has by clicking on the item, and looking at the top right of the item properties.

It's up to the map creator to add Skirmish mode, by creating an AI for the enemy team.

Hope this helps.

Cheers,

i have that subscribed but how to play then in game i click on them or what i dont know

I explained how in my post above.

oh i didnt noticed sorry:-(

but when i look in the game at workshop i have there the maps but i dont how to play them. they dont appear in skirmish.

Most of the Workshop maps don't include the AI scripts required to appear in Skirmish. Select the 'Skirmish' tag when browsing the Workshop to find maps that do.

i have that map and still it only appear in workshop manager

Are you looking in the "player" tab?

yes and i have there only all or nothing that is the only map

Which map did you subscribe to?

battle of jakku

and WW2 batlleships

on the title it has AI included

workaround: host a multiplayer game set to "private", select the map and play

You don't see this after you've subscribed?
