Ermmm, Guns, as in Troops, Tanks, Aircraft, Navies, Spies and Nukes... unless they've added more since I played. Yeah, each player is a nation... nations can join alliances... alliances can sign treaties with one another... etc. Every now and then, a huge war breaks out- I think one just happened if I'm not mistaken. It's been a couple of months since I have played.
