This is my least favorite as well. The Allies cannot win. Way too many hexes need to be controlled.Hell's Highway (which should be re-named 'A Plague of Panthers ') is the only LC product which I did not enjoy playing and have regretted buying. Perhaps it may have a certain appeal for those who are looking for a CG in which the allies cannot win and the German player can draw from an apparently bottomless pit of Panthers and halftracks during the reinforcement phases. Seriously, after a few turns there are so many German vehicles cluttering the map that it actually impairs the movement of the next mob of Panthers and halftracks entering in the following turns.
Allied air support, the small number of 57mm AT guns, and a couple of Sherman Fireflies appearing in the later turns will most likely be unable to prevent the inevitable German victory.
On the plus side, Hell's Highway has one of the most aesthetically pleasing maps which I have ever seen in the ASL system.
