Aww geez. Not sure what to say here, but this game WAS really fun. The community died quickly, probably due to a lack of advertising or something. Anyways, if people still played I would give this a really positive review. Seriously, this game can be very fun if you have people to play with.
Basically all the classes are unique and balance each other well. The maps are well designed; both visually interesting and reminescent of TFC/TF2. The art direct is great too, again very TF2-like.
Look, if you can get a group of friends together to play this, it's well worth it. I'd recommend at least 10 people, though. Aside from it being dead, it really is fun. It's essentially a Wild West TF2, and had the developers made an actual attempt at marketing this game it probably would have a decent community. As it is, it's sad to see this game so lifeless.
