You need to hope your on a team with tactics or you have good tactics . I was playing Compound yesterday on no scope and the CTs were more then holding their own.
Some good CTs tactics are to smoke where your team can jump over the wall. Go into the building right there, up the ladder and try to take out the people in the bridge.
Smoke the first entrance on the right and use the back entrance that is directly at the hostie shack.
Hide inside of the CT spawn with a silenced weapon. People won't know where they are getting attacked from. Two good places to hide are at the left entrance in the dark or in the dark area by the shelves infront of the right entrance.
Shoot out the wood paneling in the windows of the bridge. This will give the Ts less to hide behind.
Run and hide in the little shack on the other side of the wall infront of the CT spawn with a silenced weapon.
And if all else fails, smoke the main entrance and run to the hostages like theres no tomorrow.
Granted, i have only played as CT once, but these are tactics that have gotten me killed as a T or i've used that have worked well on CT. I also have no clue how well these work on the scope server.
