A gallery is an elevated area parallel and adjacent to a narrow passageway. Characters in the elevated area can easily engage characters in the passageway.
A gallery is used by a designer to create a challenge for the player. The characters in the passageway are open to attack and need to use cover if available. If the player is in the elevated area, the intent may be to enable the use of special weapons like grenades.
Similar to sniper location, with the added element of covering a specific passageway that characters are moving through.
|There is a gallery in the level “Urban Flight” of Half-Life 2: Episode 2. A friendly NPC is positioned overlooking a passageway enemy NPCs are advancing through towards the player. The friendly NPC is able to eliminate the most of the enemy NPCs before they reach the player.|
|The Halo 3 level “Floodgate” features a gallery. The player has to move up a ramp with enemies positioned on the elevated area above. The player can attempt to engage with grenades, or move up the ramp quickly and engage with conventional weapons.|
