Bunker Tutorial UI

Bunker Tutorial UI is a set of 12 tutorial and onboarding markers drawn in the field kit style, where stencilled panels with squared corners, a bone trace and exactly one signal colour. It contains four directional callout balloons, a solid and a dashed highlight ring, a corner-bracket highlight box, two step indicator states, a tap mark, a drag gesture trail and a skip strip.

Every other kit in this catalogue covers part of the screen. This one points at it, and that inverts the rules: a highlight that fills its middle hides the thing it is highlighting, and a callout that can only point one direction is useless on three of the four screen edges.

No glow and no gradient anywhere: a painted crate does not glow, and the restraint is the whole look. The silhouettes stay close to the rectangle and earn their difference from stepped shoulders and edge rails rather than from cuts, which is how stencilled field markings actually behave.

Inside that style this is the Bunker reading of it: a dark interface on a field olive palette with signal red accents, built around a single bordered frame, chamfered buttons at 152x42, hollow-cored bars divided into 12 segments, and two-tone icons on a 24px grid. Those measurements are why two families can share an art style without being interchangeable: the style decides how an edge is drawn, the numbers decide what the interface is for.

The callout ships with the tail on each of the four sides as separate sprites rather than one balloon to rotate, because rotating it throws the shading to the wrong side and a tutorial balloon is used at all four screen edges in the same session. The highlight ring and box are hollow, stroke only and no fill, so whatever is underneath stays fully visible, which is the entire point. The step dots are countable so a player can see how much of the tutorial is left, which is the one thing that keeps them pressing next.

Every sprite ships as an editable SVG and as transparent PNG at 1x, 2x and 4x, so you can drop the PNGs straight into an engine or open the vector and change a colour. Built to the same measurements as the rest of the Bunker family, which means this kit and the Bunker panel kit line up without either being resized. A good fit for tactical, survival and military interfaces.
