You will probably remember the legendary Counter Strike game, in which we spent so many hours playing... Move with W, A, S and D, write in the chat with T, put screen complete with P, go down with the c, jump with the spacebar, select weapons with the numbers from 1 to 9, recharge them with R, run with SHIFT and aim with the mouse, shooting by clicking on the left button of it.
