and game never loads.
Obviously, I cannot find the libs required on the repos.
What can I do to run it?

Any news on this?

My PC: Xeon 1230, 16GB RAM, RX-480 with ampgpu driver on Leap 15.0.
Steam is working well, surprisingly enough, but the game crashes with exactly the same error message.
Game is the Linux version.
The error: (wrong ELF class: ELFCLASS32): ignored means nothing, it appears even on machines with working COH2, as you read on the net.

Please start at new thread. This one is about Tumbleweed. Which is a rolling release where May last year is relatively old.
