No, the same thing happened to me a few times in Half Life during my first playthrough back in 98. I thought the game was broken but in actuality you're just missing a piece of the puzzle.
Thats what I thought, but there isn't anything I can move for HL in the "On a Rail" mission. I watched a play through on youtube to figure it out, and the guy just walked up to the boxes and jumped over.
The expansions also jump the same height. Maybe I need to find a patch, but I'd think it sould have arrived fully patched.
Its the censored German-version as well, so I am fighting robots, not Marines.
