This is both a playable level and an investigation into “how players absorb critical information”. Don’t expect anything too clinical because this is definitely a level where you will have to play to win.
Maps and mods that feature new voice acting.
Caught by the remaining Combine, Gordon Freeman must escape to rescue his imprisoned rebel allies. Aided by the resourceful Dawn and her insurgents, you are sprung from captivity in order to spearhead a staged breakout from the notorious Port Halen Prison.
But before you can get there you must loose your Combine pursuers and make your way through a wilderness long since overrun by the zombified.

“The Game Master’s Lair challenges the player with three “Classic Game” Puzzles inspired by Milton Bradley’s Simon Game, ATARI’s Breakout, and the game show “Let’s Make a Deal.”
The Level is intended to fit within the Half-Life universe, but showcase unique gameplay atypical of a combat oriented First Person Shooter. The player is armed with only the basic physics cannon and must solve each puzzle to advance. The level’s difficulty must be accessible to all skills levels.”

The death of the Nihilanth threw the Xenian army into disarray, and the subsequent portal storms stranded many on Earth in the wake of Combine occupation.
After once more having to endure existence beneath the totalitarian boot of their cosmic nemesis, they have searched for a way out. Now, buried in the heart of a dilapidated university, they’ve found it.

The episode takes place during the events featured in the original Half-Life; specifically, the episode entitled On a Rail. The player plays John Skinner, a cleaner who wears a similar HEV suit to Freeman, and is hence mistaken for him by the military. Skinner’s objective is to destroy a surface-to-air missile launcher, which the military have brought in to take out the sattelite delivery rocket being launched by Freeman.

This mod features some intense action scenes, but most of these come later on, much of the earlier parts of the mod are focused on adventure and storytelling.

AT 30,000 FEET… you are almost 6 miles (9.7 kilometers) above sea level. The human body is not made for these conditions. Temperatures are can plummet to -60F (-51C), the brain is starved for oxygen and each step is a new experience in pure agony. It’s difficult to breathe. It’s difficult to think. It’s difficult to move. And you still have to endure another 444 feet (0.14 kilometers) to get to the peak. So much for the good news.

The Citizen is set parallel to the events of the original Half-Life 2. The player takes the role of an ordinary man, pushed over the edge by the oppressive regime controlling his life.

Author’s Note
“The Lighthouse is my single player project I did for HL2. I wanted to break out into some larger, more expansive enviroments as well as work in a more realistic environment for a change. The map features a mix of going at it alone as well as working with a small “squad”.”
