Crossplay for local games:

[✠DonaldAlex TrumpJonesFreeman]

It would be awesome if I can cross play with friends on PS5, and not have to pay profuse amounts of money to run something that probably wouldn't work. Thank you.

If you're on a PC : The DS software itself is free.
If you're on another Console : You're on a console, and with complications, you can't, as differing platforms.

Cross-play is automatic. "DS" (dedicated server) software isn't necessary. Set the game to online and have the other user direct connect to the computer's IP or localhost as the address.

There is a limitation with playing cross-play games. The worlds aren't as large because game consoles can't handle the massive size of the full Star System world.

This limitation is why it may be a better option to use the Space Engineers Dedicated Server Manager. We can set a game hosted through that program to be the limited worlds so console users are able of joining through a setting in the config file.

Hi, I recommend to join the SE Community on Keen Discord to have access to the server ads channels where server admins share their crossplay compatible server information.

Best to join available Public servers set on compatibility mode for crossplay, the ps version is very limited compared to the Steam version so we must join crossplay compatible servers.

All can join the SE community from the Discord permalink added to this pinned :
https://steamcommunity.com/app/244850/discussions/0/4622335767039372629/

Once on the Keen Discord -> Go to the Role selection channel to choose PC role, Ps role and Xbox Role to unlock all channels -> go to the "server-ads-Xbox" and "server-ads-ps" channels to try all availble servers.

No need to buy a second PC to run the SE Dedic or rent a server set on compatibility mode.
