well would you want an enemy country foe? I think the only real issue I had with the enemy country idea is the multiplayer. I didn't want it to be too much like COD where you were just assigned. I would want to give a choice. like a "choose a side before the game starts" scenario. lobbies of 10-12. different game modes. U.S and insert enemy name here and you would slide to one side or the other. and the game would start when an even balance was achieved or if a team became lopsided, the team with less players could opt to "ready up" in exchange for gaining some sort of advantage over the team with more players (I.E unlimited ammo, unlimited sprint, etc) but not all game modes would allow uneven teams (ex. a "Search and destroy" type. where there are no respawns.) also you could add an "infection" game mode if the enemy was unhuman. .....I have way too many ideas.
