ASG Lab

ASG is a possible origin story behind the Valve Handheld Portal Emitter. In this game, the player must locate the marble device and solve a number of specialized puzzles as they progress through the story. This is an exciting team project from nonPareil Institute in that it was built entirely using the Hammer design tool.

The Story...

A secret U.S. government facility is doing interdimensional transportation experiments in the 1940's in hopes of finding a way to prevent future wars. At an undisclosed location in the southwest borderlands of America, an experiment goes horribly wrong, and a task force specialist must be called in to investigate. The latest reports show that a portable spacial-rift device is theoretically possible if the precise combination of antigravity, electromagnetic, and strong forces can be precisely combined. But when a doorway is opened to the unknown, the entire tri-state area is in jeopardy of vanishing into the void!

Design Theme and Tone

Setting the tone

During World War II, the United States entered a time of military and industrial productivity, espionage, political subversion, and unparalleled scientific research in order to prepare to meet the Nazi threat. Along with Bletchley Park in England and Los Alamos next door in New Mexico, the United States launched other secret failities used to conduct research. Here, among the beautiful peaks of the high desert's windswept buttes and mesas, another secret underground facility pushes this scientific research to its limits. In an attempt to open a rift in the fabric of reality itself, their contained labaratory experiment went much farther than it was supposed to. That is what happens when your calculations are a few decimals off...

Players will feel the intrigue of a beatiful farmhouse on the surface, with a government installation underground that connects a warehouse, barn, and a smokestack forge. Sometimes it is better to let an experiment fail, but when the player reopens the experimental rift, they must escape with the secret and secure the rift before it tears the world apart!
