Crosshair editor
Press the apostrophe key during a match to open the crosshair editor. You can change color, thickness, spread, transparency, a center dot, and whether the crosshair expands. Turning dynamic expansion off is a common choice because the expanding crosshair hides the angle. It is a preference, not a ranked requirement.
There is no single best sensitivity in the public material. Set the in-game slider, then the Roblox camera sensitivity, and keep that pair still while you practice counter-strafes. Copying another player's DPI without their in-game slider does not reproduce their aim.
Viewmodel X, Y, and Z sliders and the FOV slider move the gun model and the field of view. Use them to uncover the middle of the screen. Published coordinate sets are personal setups, so this guide does not treat one triplet as the game's default.
Clutter and frames
Impact effects, muzzle flash, and ragdolls can be disabled in the game settings. Bullet tracers are worth leaving on if you need to see shots through smoke. If frames drop on a heavy map, lower Roblox graphics manually and disable Map Details. Raise the Roblox frame-rate cap only as high as the device holds a steady number. A cap you cannot reach does not make peeking more consistent.
Radar refresh and radar size are separate sliders. Players often raise refresh so the minimap matches movement, and shrink the radar so it does not cover a site.
Keys that surprise new players
Crouch is Ctrl or C. On a Mac, Ctrl does not crouch, so use C. Walk is Shift. Inspect is F. Drop is G. Buy is B. Team menu is M. Scoreboard is Tab. Public chat is Y or slash. Team chat is U. Music mute is P. Vote kick is 9 and requires 24 hours of playtime.
While spectating, left click cycles players, Ctrl frees the mouse, and Space changes the camera. Unranked Competitive limits you to first-person views of living teammates.
