Half-Life 2 SP Zombie Onslaught Map

is fairly well done in most aspects, except for the fact that the zombies can't actually overun your position. Another issue was the fog, it was done a little too heavily, so you can't see all that far in front of you. Also, you can see the edges of the map, where the walls come up, which isn't really a problem, it's just a little odd. On the plus side, you don't have too many Combine, and atleast Fast Zombies can reach the outpost and actually get in there. With more zombies and a little more work, this has the potential to be a good map.
Finally another single player map! This map is the standard zombie "ladder"-like level, with unlimited waves of zombies continually trying to overun an outpost of Combine soldiers, and you. The map
