About Grenade Case On This Short...
It seems that is a high-explosive grenade i think...
But, uh...That was more of a flashbang or a smoke grenade than a grenade in CS...
I liked it they moved very well not like other stupid animations and you actually used a picture from the game and the sound at the:Counter Terrorists Win.Its also from the game.Next time try to make it longer not with a story just longer.
You should do tutoirals on how to do this.
