| It's explained nowhere and I have to chase that guy at the construction site. Which keyboard key(s) are used for climbing? Please help me.|
Its actually explained how you do it. And its explained in that exact mission where you follow Ivan up the ladders on the construction side.
Also you can press sprint while climbing up or down to go faster.
(Check the "Brief" in the menu if you missed the isntructions on HOWTO use ladders.)
