I'm new to Counter Strike, and CZ only just completed today, personally I consider it worth downloading, the gameplay is fantastic and the graphics are good, but not extreme; not to an extent where fellow gamers with crappy 64MB SiS cards can't play it.
So, my query involves asking how might you climb the ladder during the objective: "Rescue Delta Operator at his last known location?", it's quite high, and the cut-scene previously showed that the Delta Operator did manage to climb it. BTW, I Googled for an answer and in CS (1.6), it says for high jumps use Space + CTRL, but that doesn't work.
And I did do the training, but that was a small ladder.
