I was on one of his testing servers and I didn't think it was very fun. In my opion if you want to play CS than just go and play it on steam, I didn't like how the charactors were so slow, the HUD was annoying with a standard red only displaying your ammo, and the health was low. I think there's already an intresting fighting method for blockland right now and to add another way I think it will just flop.
