I don't really agree with that at all. Hunters are deadly when you separate survivors. On fire and you are doing some serious damage, not to mention the huge jump damage if you get up high.
Smokers are the most useless class because they do bugger all damage, are easy to spot and hear. They are...
Not really that impressed with the box art, portal's is the best because it's simple. TF2 doesn't seem to work well for me. EP 2 uses a good image but clutters the front space up. Just my opinion.
I don't know what version I played, but it was the first release I think. I didn't like it, not because it had bugs or anything, but because the gameplay wasn't my style. It was pretty polished. I guess I'd be willing to give it a try, but I doubt the core gameplay has changed that much. Kudos...
