Dave Johnston is best known for creating de_dust and de_dust 2, but he also made other maps for Counter-Strike. No, I’m not talking about cs_tire, the reddish-brown retirement home which was cut from an early beta. (That’s me establishing my CS credentials). I mean de_cbble, the quaint castle-set map.
Over on the Counter-Strike: Global Offensive blog, the CS:GO team have written about their work in re-creating and updating de_cbble for the new game, alongside an entirely new map they’re adding soon. They say mean things about the old de_cbble.
