Sequence number. Follow the numbers to complete the level! Repeated numbers indicate transitions between parts of the same map, or between different maps (often via an elevator or ladder). They can also indicate similar stops along the same route (to trip a series of similar switches, for example). |
 |

 |

 |
Underwater hatch or duct. Top icon is used in vertical map sections; bottom two icons are used in standard overhead ("top-down") map sections. |

 |
Crate or barrel. Opens using pistol. |
 |
Reinforced crate. Opens using heavy weapon or adjacent explosive crate. |
 |
Inert item. This color (size varies) usually represents various inert structures (unopenable crates, non-functional computer consoles, etc.) that make up part of the level topography but normally cannot be interacted with. Note that some of these items (chairs, for example) can actually be manipulated--usually destroyed--in some cases. |
