Grim's first mission, the Seafort one, is one of the best Splinter Cell levels I've played. For me, it ranks alongside CT's Bank for quality and available options. Really impressed.
Also, had a lot of fun on SvM Classic. Just as nail bitingly good as I remember it.
Currently trying to Ghost through the villa in South America. Any tips for crossing that first courtyard with the dog? I tag him to keep an eye on it so I can keep away, but Sam must be wearing Pepe Le Pew's aftershave or something because that little fucker sniffs me out from miles away.
If you want to leave them undisturbed you just have give them a wide berth, watch their patrol paterns, and move fast. Otherwise the Tri-rotor works really well.
