Players discover a new use for a familiar item. Their understanding changes while the tool’s properties remain the same.

1. Available inventory tool

- Apply the discovered property consistently in new contexts.

## How it works

Knowledge expands the use of already available tools.

## Variants

### Variants and applications

<a id="family-02-variants"></a>

- Secondary function of the item. The tool has additional uses that do not follow from its original role <a id="variant-metroidbrainia-02-01"></a>
- Impact on the environment. Weapon or ability interacts with architecture, mechanisms and materials <a id="variant-metroidbrainia-02-02"></a>
- Using the shape of an object. The length, thickness, contour or orientation of the object is important: it can be turned into a bridge, strut or template <a id="variant-metroidbrainia-02-03"></a>
- Dependence of function on state. A wet, heated, charged, opened or damaged object behaves differently <a id="variant-metroidbrainia-02-04"></a>
- Unobvious portability. An object perceived as part of a room can be taken away and used elsewhere <a id="variant-metroidbrainia-02-05"></a>
- Hidden interactivity. The decorative element turns out to be a full-fledged object of interaction; an open rule helps recognize similar elements <a id="variant-metroidbrainia-02-06"></a>
- Obstacle as a tool. A hazard, trap, or hostile object is used to solve another problem <a id="variant-metroidbrainia-02-07"></a>

## Context and limits

In metroidbrainia, progression depends heavily on the player's knowledge: an open rule changes the available actions, routes, or decisions. 91 mechanics in 12 groups, progression techniques, training techniques and edge cases are stored here. For a project, check what knowledge is acquired, how it is derived, what it reveals, and where it is reused. Specific game solutions are not disclosed.
