4 Quick Summary This singleplayer Half-Life 2 level takes place within an old underground temple that located within a mountain. The game space consists of two main areas: a small desert exterior just outside the entrance to the temple and the interior of the underground temple that contains five dangerous puzzles. The player s objective is to traverse through the temple as quickly as possible in order find Dog s spark, which is located at the end of the temple, before he dies. Each puzzle within the temple has a side passage that can help the player skip the puzzle. However, using these side passages may add unnecessary time to getting to the end of the temple. Gameplay Overview The primary focus for the player in Quest for the Spark is to traverse through the underground temple as quickly as possible in order to obtain Dog s spark, before he dies. The player goes about doing this by making a choice each time they run into a puzzle, which is to either: solve the puzzle as quickly as possible or to use the side passage to get past the puzzle without solving it. Both of these options have positives and negatives to them depending on the situation. If a player is having taking too long on a puzzle, taking the side passage may be quicker then continuing to struggle with the puzzle. However, each side passage contains a single guard with a good vantage point on anyone coming up it, which may slow the player down some. In addition, solving the puzzles is the quickest and most direct route through the temple as long as a player is not stuck at it for too long. Solving a puzzle also has the added bonus of giving the player a good vantage point against the guards who occupy the side passages, allowing for a quick and easy kill. This constant decision making each time a player comes to a puzzle provides a certain type of strategy in beating the level. The combat within the level is quite simplistic. The only forced combat is at the beginning of the level where the player must fight a few antlions before entering the underground temple. The combat within the temple is optional, as the player does not have to take any of the side passages where the guards are located. Since the combat within the level is quite sparse, the difficulty in the level comes from the race to get to the end of the temple as quickly as possible by solving the puzzles as quickly as possible. This time pressure gives the level a sense of difficulty. It is also important to note that as the temple is underneath a mountain its path goes up hill and provides a preview of the puzzles to come as long as the player has the sense to look up.

Level Position in Campaign: o Mission Location Quest for the Spark is the last level in the campaign, in which Gordon must get Dog s spark back after the combine steal it to power an old underground temple. Theme: dark and foreboding with a sense of tension Mood: tension and awe Setting: middle of the desert in an underground temple Time: noon Season: summer Weather: hot and arid Mission Difficulty Starting: 2 out of 5 (fighting the antlions) Middle: 3 out of 5 (spelling out water by jumping from tile to tile takes some time) Ending: 4 out of 5 (well puzzle takes time to figure out how to solve) Kyle Brennan Page 8 of 43 Level Design Document

9 Mission Metrics Play Time: 5 10 minutes Physical Length: 18,432 hammer units Physical Area: 6,400 hammer units wide x 8,704 hammer units long Max New Characters: no new characters, using the standard antlion and combine soldier Max Visual Themes: 2 o Desert exterior sandy terrain and yellow rock o Underground Temple dark yellow and brownish stone Technical Details Level Atmosphere/Mood Quest for the Spark emanates a dark and foreboding feeling with a sense of tension. This comes from both the visual theme of the underground temple as well as the main objective of the level. Listed below are some ways in which the level helps to give the player this dark and foreboding feeling with a sense of tension: The temple hallways are dark with old and warn yellow/brown stone, lit only by the warm glow of wall torches Dirt and rocks from the walls falling apart cover the floor The pathway of the temple steadily climbs in elevation and if the player looks up they can see the next puzzle in the distance giving them a foreboding notion of the next puzzle to come Tension is derived in the level through the use of a 10 minute countdown to Dog s death which gives the player added pressure to getting to the top of the temple as fast as they can The puzzles are littered with the remnants of those who came before and failed, adding some additional tension Some of the puzzles also give the player a sense of awe with seamlessly unending chasms that may mesmerize the player Before each puzzle an eerie voice gives the player a hint on how to complete the puzzle The entrance into the temple also gives off a foreboding feeling due to its large size and the fact that the player cannot see inside until they walk through it The low sound of the wind blowing throughout the temple provides the player with some ambience Kyle Brennan Page 9 of 43 Level Design Document

10 Story Introduction o Gordon Freeman finds himself in the desert next to a dying Dog. It is up to Gordon to go into the nearby temple and find Dog s spark before he dies.

12 Desert Exterior The desert exterior is a hot and barren place. The area consists of sand dunes, a few cactuses, and sand colored rocks. The entrance to the temple is in the northern area, made out of carved sand stone inside an opening of a rock face. The sun shines bright in the sky revealing every detail of the ground below. At the player start, Dog is slowly dying and the crashed car sits near an impassable ramp. Antlions also wait in the ground for the player to come too close.

17 Underground Temple The underground temple is a dark and ominous place. The warm glow of wall torches lights up the slanted temple hallways. Decaying brown/yellow stone make up the walls, floor, and ceiling. Dirt and rocks litter the floor from the old stone-walls falling apart. The various puzzles populating the temple contain mutilated bodies of those travelers who came before. Stone doors sit at the end of each puzzle and combine sentries stand waiting at the end of the alternative paths around the puzzles.
