Played for some time and can't say I found a route to the win without some tricks. Are tricks part of the intended way?
Nice level although I didn't found a very good solution imho... Thanks! Spoiler I guided Rs to the last zone before the win to block the zapper and then cross that area quickly to the win with B.
Spoiler: Hint 1. Other than the bad zapping guards, some prisoners are equally dangerous. So not to let them out when you are figuring the route; 2. There is a short window to go through the inner yard guard, the gate guard should be blocked at beginning if you want to go through the gate; 3. In the film, Andy crawled through a long dark tunnel and set himself free. The redemption is within. 4. B has needs some courage to step in the tunnel dig by himself.
