Was George Orwell an Optimist?
Mario Pavone - Dancer's Tales
In the game's description is written that this is an update of "Grunt". Does this apply also to the scenarios? I mean, are these basically the same but adapted to the new rules / changes in the game?
Search & Destroy has a basic game that amounts to an updated Grunt with the Grunt scenarios. It also has an advanced game with additional rules, units, and 11 new scenarios. The scenarios represent historical actions from 1965 to 1967.
