This build is version 8.1, has a file size of 90M, and uses the package name com.headupgames.bridgeconstructorportal; because it is a re-signed file, it cannot be installed as an update over a version obtained from the official app store.
About Bridge Constructor Portal
In Bridge Constructor Portal, you will combine the skills you learned from the Portal games and the Bridge Constructor games. You are tasked with building bridges that allow Aperture Science vehicles to cross the many gaps and other obstacles located throughout the Aperture Science Enrichment Center. In the base game of Bridge Constructor, you are tasked with connecting various supports to create a path for the bridge. In the game, you are using certain portals to create a path where a support for the bridge can be placed to create a physically stable path for the Aperture Science vehicles. If a player creates a poor bridge design and a vehicle falls to its doom, the player will have to restart the level. Throughout the game you will have to use your skills as an engineer and as a problem solver to overcome the many hazards of the Aperture Science labs.
GLaDOS plays an important part throughout the game and will give players the info they need for the current section of the game. As the overseer of the test facility, GLaDOS will introduce players to new game elements and mechanics. This is a way to allow players to learn the limits and abilities of various components and give players the info they need for more complex situations. Without GLaDOS’s instructions, players would not learn the advanced construction tasks they will have to perform throughout the game.
Portals are a major aspect of the game based on the source material, and function similarly to the portals seen in the source material. The portals, as mentioned previously, are color-coded, and more often than not, start with the standard orange and blue. When a vehicle passes through an orange portal for example, it will appear on the other side of the game environment through the blue portal. The mechanic of non-linear movement allows players to traverse the game environment that is made up of disparate rooms that are not physically connected to one another. As the player progresses through the game, the number of portals increases, and new color pairings of portals, like red and green for example, are introduced. Player orientation of a vehicle relative to portals is critical, as a vehicle will keep the same direction and momentum when exiting a portal as it did when it entered. This adds an additional complexity to the design of bridges as players must build structures that funnel vehicles towards portals, as portals will be placed off center.
The game relies on nodes and connections to create bridges. Nodes connect in various ways to make different structures. Each structure or support has a limit to how far it can reach. This requires the use of multiple nodes to support larger gaps. The game rewards players who figure out where to properly distribute weight by limiting how much a particular road surface can hold and forcing players to use different types of support structures. The game presents different obstacles that require players to create large structures that span many parts of a room to reach a goal. The player’s attempts at creating structures that span many parts of a room are tested and evaluated to see if the goal was reached. Making adjustments can help achieve the desired outcome or goal.
Convoy means getting a full group of vehicles to the end of the level. Getting a single vehicle across the bridge might satisfy the convoy requirement temporarily, but the goal is usually to get repeated use of the structure without causing a collapse or structural fatigue. The game tracks how many vehicles make it to the end of the convoy and the player has to modify the design of the bridge to account for repeated stress of large, heavy units. The game balances a budget for the materials used to make each bridge. This budget system encourages design efficiency and promotes cost-effectiveness to avoid wasting materials. The transition in the environments of the levels reflect the balance of the budgets, with simple single-room layouts first and more complex, challenging multi-room layouts later. The goal is to understand both bridge building and the portal systems. Players must account for as many variables as possible in their design including the speed of the vehicles and the structure of the nodes and the support cables.
The game also includes environmental factors and hazards that must be taken into account during construction. Most obvious gaps that need to be spanned are just one aspect of the testing process in the Portal universe. Players must also beware of elements that can disrupt tests and destroy vehicles. As in real life, the placement of bridges must also be considered in relation to possible hazards. Routing of vehicles in a test track must also take possible obstacles into account to ensure survival of the vehicles. These obstacles require players to construct safe paths and protect vulnerable areas on the test track with shields and pathways. As a physics sandbox, the game encourages players to experiment with a myriad of different configurations of portals and what effects they have on structure and the elements in the environments. Within the Aperture Science Enrichment Center, players must use their skills in engineering, bridge construction and spatial awareness to overcome the challenges the game presents. Players must integrate their knowledge of the systems of bridge building and the systems of portal navigation to solve the challenges in each of the environments.
