Cause And Effect mod for Half-Life 2

OVERVIEW
Cause And Effect is a story-driven, co-operative total conversion of Half-Life 2. We're aiming to create a world which, in an odd twist, contains zombies, scares you, and remains true to the realistic approach of the other facets of the mod.

Your main objective is to escape the city of Braxton, that you, for all intents and purposes, have been imprisoned in by the military and local law enforcement. Using whatever weapons and items you can scavenge from the area, and using the environment to your advantage, you must keep yourself and your friends alive, and get the hell out of the city.

You don't want to be the last one left.

FEATURES
We're planning to implement a number of innovative gameplay elements into the mod. A few (yes, a few) examples are as follows:

+ Unique two-tier health system. Incorporates bodily damage and consciousness into a system akin to real-life. Think Halo, but more realistic.
+ HUD-less. Instead of textual data or symbols, we will use visual cues and "tangible" indicators to display important information such as ammo and health.
+ Scavenged weapons. Not only can you use pistols, knives, and baseball bats, you can also pick up any reasonably-sized object and use it as a weapon.
+ Broad combat system. Every weapon has multiple attacks and functions, such as iron sights, push attacks, and scalable melee attacks.
+ "Tech" items. Items or weapons that have special or specific uses, like a flashlight, or a hammer.
+ Breakable weapons. Most weapons will physically degrade over time, based on how they are used.

STORY
The story, though it has gone through many an iteration, is still being kept under wraps. But don't despair; Even if it were to become public, it would only leave you with more questions than answers...
