There are two games which I remember both were very fun, but I can't remember the websites.

1- A topdown 2D tank online game, strategic kinda, lots of people in an outdoor place. I kind of remember it being Tanx or something, either shockwave or flash game.

2- It's called something like vietcong or viet-something, but it was also 2D and topdown and you had to move around as a team defeating the enemy, also online and shockwave or flash.

Help would be greatly appreciated.
