Cant find anything on these modes. How do they change the game? I can see the obvious, but I'm thinking there is more to know.

What kind of choices do the servers get in setup for each type?

Thanks

Standard includes map and all HUD elements
Pro does not include the map or ammo counts, and you kill people a LOT quicker. It's more commonly known as 'hardcoe' mode.

Thanks.

Classic I believe doesn't let you use Armor or Stealth modes, basically you don't have the nano suit.

I have no idea what Solo is. I would GUESS that it means people can not play with anyone on their friends list?
