The main game is awesome. The expansion, High Treason on the other hand has a gamebreaking bug in one of it's early levels that makes progression impossible without skipping a chunk of story. In the naval combat/sub hunt mission a sound bug occurs which also results in all your ships freezing. this makes the mission absolutely unplayable and thus... Amazed that for such an old game it hasn;t been patched/solved yet despite many others reporting hte same bug on steam etc.
