Superb map, you can really see the effort the author put into this everywhere.
A great duel map; i have already had a lot of fun on it. It takes some time to learn the topology of all those hills and cliffs around your base.
Disabling scavengers turns it into a well-made medium-sized duel map; The only thing that makes it slightly non-canon is those oil drum packs scattered around the map, which boosts the initial development and makes the players race to acquire them.
Easy/medium versions are a bit overoiled, imho.
Its nice for new players that want to learn. Despite haos comment I think - with scavs on (and I guess it is intended for scavs on) - its a pure MG map. Without scavs the map is more interesting (to me) though.
