The game starts when Dolores in a dream wakes up and finds herself in the childhood home she left behind all those years ago. As she starts to wander around the big southern style mansion memories from the past, she thought she had left behind, keeps appearing before her.
Check out the description on how to install & run the game.
Note: We have not preformed any measures on what type of hardware is required to run Dolores, but a good rule of thumb is that any machine complient with the recommended specs for Half-Life 2 should be able to run Dolores. However, if the machine barely surpasses the minimum requirements for Half-Life 2 - then you're in trouble.
Just download and run the Dolores_v05a.exe file
After the install you need to start (or restart) Steam and Dolores should show up on your Games list. Then just double-click and you're off.
