To disable the hud in Hard Reset, there are two methods:
1. Easy, flawed, and temporary
2. Complex and permanent.
Open the console in game by pressing Ctrl and ~ at the same time.
type: r_draw_weapon 0
that will remove the hud, the weapon, and in game interfaces (like weapon upgrades and signs).
To disable the crosshair, type: r_draw_hud 0 (disables menus too.) To re-enable either command, change the 0 to a 1.
To bind the command to a key, type: bind +h "r_draw_weapon 0"
Replace 'h' with the key you want and "r_draw_weapon 0" with whatever command you want.
Complex & Permanent Method:
This method involves editing game resources. Back up any file before editing it. A mistake may require a reinstall if you don't.
Go to your game directory. Find the \data\data_10_scripts.bin file. Change the file name to data_10_scripts.zip. Open the file. Browse to the directory: data/scriptsbin/gameplay/base_templates/item/ delete the "hud.nut" file. exit the .zip file. change the name of the file back to data_10_scripts.bin. Start the game, and your hud will be gone.
To disable intro movies in Hard Reset, open your \data\misc.bin file (rename it to misc.zip first). delete the data/cs/intro.lst file. rename misc.zip back to misc.bin. Start the game and the intro movie will be skipped.
