Actually if this a strategy game recommendation thread, I've been playing
Defcon since it came out on Friday. It's available for download through Steam or their Website for only £10, the IGN review is
here and it scored 87% in PC Gamer.
If you've ever seen the film Wargames you'll love it. It puts you in charge of a six equal continents strategic defence forces (subs, radar, aircraft and silos) and Navy. The counter starts at Defcon 5 where you can position your forces and ticks down to Defcon 3 where fleets and aircraft and ships can engage one another and finally Defcon 1 where nuclear weapons can be used. There's a few scoring modes but the most popular gives you 2 points for every million civilians killed and -1 for every million civilians lost. The game is great fun especially online with 6 players and all the alliances and backstabbing that goes with it.
