I've always liked the Blitzkrieg series - perfectly balanced, old-school realtime strategy with great detail and loads of explosions. And for a game that barely improved between sequels, this mission pack adds two new campaigns of rock-hard levels, loads of new units and even a slightly improved engine - not that there was much wrong with the old one. Alas, missions tend to consist of the same level played out in slightly different terrains, with the same survive/reinforce/survive mechanic throughout. It's also infuriating how few units they allow you to call on each level, given there are 250+ available. Still, if you like your wargames challenging and bristling with tanks, this is highly playable stuff.
