Back to the ladders, very much like Quake 3 games for me
Run to the ladder the wrong way and as your falling quickly rotate 180 deg to grip the rungs.....easy (that's why the ladders have the safety cage at the top )
Just thought Crouch jumping problem may be because this mod introduced "Sprint" and you needed Fwd+Sprint then duck+ Jump, in the (wired warehouse) and Teleporter...well I did anyway !
I did have some stuttering in some earlier levels and chronic stuttering right at the very end..anyone else ?
As suggested, I hope Valve pays these Guys to do a Blue shift etc..with their maps. Some of those later Maps/textures were better than anything Valve release in the whole HL series.
