Go to
http://www.everybody-dies.com/downloads/ and download the demo...about 60M I think.
If you ever watched the film Wargames when you where younger...and tried to hack into the pentagon on your ZX spectrum 48K or Commador 64K...then you'll find this game a hoot!
The demo allows you to play either against the AI or online against one other opponent. For £10 you can buy the full version which is exactly the same, but allows you to play against numerous other players at once...full blown nuclear war!!!
Anyone fancy a game..let me know...I'm on there as Harv748 also.
Sleep well ;-)
