The following allows you to skip to certain checkpoints or entire levels:
In half-life 1, a console command called map name ca0a0 would bring you to the loading screen of Welcome to Black Mesa. ca0a1 would be after the tram I believe. Try typing map name and pressing tab to see what maps are available. The lower the hex values if any the closer to the beginning you will be.
Counter-Strike 1.5's console command to change levels which was ported to Condition Zero was changelevel [mapnamehere] so be sure to also keep that in mind as a possibility.
This is just a note from an old user of the first engine's console, it's not guarenteed, but since I know Deleted Scenes was built on the same engine then I know that Most of the same commands will work in it. (I.E. sv_cheats 1 enables cheats and impulse 101 gives you all weapons etc.)
If you wish to have hard facts I will update this with a list of console commands.
Some level names that may work are:
- Recoil (file name known as cz_recoil, Source)
- Sample
changelevel cz_recoil or map cz_recoil
- Lost Cause (possible to be known as lostcause but no confirmations yet)
- Sample
changelevel lostcause or map lostcause
SIDEBAR: Please note that if you're being bounced repeatily to the main menu and the console commands do not help, then it may be that the engine cannot open your integrated video card! Some cards have been known to not be able to run video games when they are integrated with your CPU. This is because some if not most integrated chips before the Core 2 Duo series did not support DirectX or OpenGL. This made it somewhat impossible to render any game under those chips.
TL;DR Sidebar If your graphics card is integrated you may not be able to play most games that require rendering of graphics.
Create a file called autoexec.cfg in your Steam/steamapps/common/Counter-Strike: Condition Zero/cscz/cfg.
I haven't double checked the folder names, so you'll have to correct me on that one.
Edit the file and add the following:
bind ctrl +duck
This file will be executed everytime the game starts, and thus binding your duck key to the control key every time.

You're missing a model file, this can be retrieved from here
You will need to place this file in the /models/player/leet/ directory.
If the problem persists for a different model you can just reinstall the game and apply applicable patches or search here for the files needed.
