Okay, I just remembered today of a game I used to play with my brother when I was little... probably when I was like 7-8, so about 6-8 years ago. The game was a sort of military game. You commanded a person and had to do military missions, like infiltrate bases, blow up things, kill certain people, etc. You got to use different characters for different missions. It was for the PC, obviously. I remember there was one mission where you got to be a spy guy, and when you went over an enemy with the cursor, a syringue ( spelling...?) would come up, and when you clicked it, the spy would go up to the enemy and inject them with something that made them die instantly. It was REALLY cool. There was also another mission later on where you got to use a Russian spy girl, I believe. I'm not sure, but I think the look of the game was like C&C-esque. It was not first person. I honestly have no idea what the game was called. I know I gave a horribly vague description, but hopefully someone can point me in the right way.
