Currently I'm making an aim map for Counter-Strike 1.6 with several aim practices that usually don't require terrorists and counter-terrorists to kill eachother.
1.) A shooting range that when you press a button it creates a hostage out on the field.
2.) A shooting range that when you press a button a clay pidgeon flies out and you shoot at it with a shotgun.
3.) Just the middle of de_dust2 where spawn campers shoot at people that pass through with awp. There will be an easy, medium, and hard mode for awpers to advance in reflexes so that at hopefully in a real match they'll be able to awp anyone that passes through those double doors.
I hope nothing like this has been done before. Feel free to flame me if you don't like my ideas.
