Hey AZTiger98 and welcome to SOW ..... If you look below the Chickamauga mod you will see "Shiloh Redux" - it's a SOW redo of the original TC2M Shiloh mod.
Only 2 scenarios are available at the moment, but more are coming.
Only issue with OH2 now is that it doesn't end when it should ..... went past the one hour and I had to end it myself and because of which my score did not register.
