The developer included both games ("Brothers in Arms: Road to Hill 30” and “Brothers in Arms: Earned in Blood”) but as separate apps. By default, launching the game in the MacGameStore will launch the second game, “Brothers in Arms: Earned in Blood.” To play the first game, the "Brothers in Arms: Road to Hill 30” app will need to be manually launched from the Finder or manually added to your MacGameStore app’s library of games.
To add “Brothers in Arms: Road to Hill 30” to your MacGameStore app’s library, go to the MY GAMES - ADD YOUR OWN area of the MacGameStore app, and click the plus symbol (+) at the top of the window. A dialog sheet will descend that says, “Select a game to add to My Games.” Click the “Browse” button, and then press “Command-Shift-G.”
Paste the following into the “Go to the folder” field:
/Applications/MacGameStore/Games/Brothers in Arms Double Time/Brothers in Arms Double Time/
(If you have chosen a different location for your MacGameStore app to keep your games, you’ll need to adjust the game’s path, accordingly)
Click the “Road To Hill 30” app, and then click “Select."
You will now be back at the “Select a game to add to My Games” dialog, and now the “Title” field will be filled in with “Road To Hill 30” and the “Game Path” field will have the game app’s location. Click “OK.”
“Road To Hill 30” will now be listed in your MY GAMES - ALL GAMES library as well as your MY GAMES - ADD YOUR OWN library in the MacGameStore.
