Stopwatch hud icon from Sulfur, indicating the final point is a timer instead of a normal control point.
The "Main" text is baked into the icon, just as with the Main icon on Steel.
How to use
Set the HUD icon in the team_control_point entity, using these filenames:
The "_locked" variants are found automatically by the game.
Important: HUD icons likely need to be packed manually!
Free to use as-is without credit!
Please ask me about modifications.
