Your level is good,but not much.
Id say the secrets are well hidden.
The eyecandy is ordianary and the music gives the player the feeling hes in space well.
The music effects you put in make the player thimk hes in a real combat zone.
The rules aint as the real Couter-Strike is,but it looks like a Counter-Stike level.The ammo is well spreaded throught the level.As one of your first uploads,you did well.
For me,the rating for this level is 6.0
