Deadlock Crosshairs

Turn on Settings > Interface > Dev command console once. After that F7 opens the console in game. The launch options -dev or -console also enable it.

No. Deadlock has no share code. Crosshairs are shared as a chain of citadel_crosshair_* console commands separated by semicolons. Every crosshair here copies as that chain, and the editor can import chains from any other site.

Most pros use a small static cross in green, cyan or white with thin lines and little or no center dot. The pro list shows the exact settings of players like Hydration, Dimov, Lefaa and shroud, mostly taken from their own Twitch !crosshair commands.

Some heroes, like Celeste, Paige and Doorman, use a themed reticle that replaces yours. Turn off Settings > Game > Themed hero reticles, or tick the matching option in the editor before copying.

That is Reticle motion: the lines spread with your weapon's inaccuracy. Turn on Static lines in the editor (citadel_crosshair_pip_gap_static true) to keep them fixed.
