About Project Three

Project Three - about the game
Project Three delivers psychological first-person survival horror in an alternate fan-made Half-Life universe. After a resonance cascade, a routine commute erupts into combat against alien creatures and US army forces, with reality twisting through immersive storytelling. Players defend with melee crowbar blocks that cut or negate damage, alongside firearms requiring manual magazine refills from scavenged rounds. Survival hinges on tactical choices amid unforgiving chaos, facing headcrabs in packs, relentless zombies, agile manhacks, fixed turrets, and tripmines. Adaptive enemies and deadly hazards demand precise ammo management and planning. Fans of tense, atmosphere-driven indie horror thrive on this high-risk combat loop.

What is Project Three?

Project Three a psychological first-person survival horror made by one person focused on atmosphere, story and defending yourself with melee and weaponry against several creatures. The story is set in the alternate fan-made universe of Half-Life, Valve Corporation's successful series.

The story plays with a different idea taking place after a resonance cascade, an innocent trip to work suddenly turns into a fight against an alien race and the entire US army... but what if the truth is a little different.

Who will refill your magazines? Learn about survival elements.

The game also features survival elements that make the gameplay even more engaging. One of them is the crowbar, which allows you to block enemy attacks—reducing or even completely negating incoming damage.

Another key element is weapon reloading. Unlike traditional games, you don’t simply collect ammunition; you have to manually load rounds into your magazine. Your weapons are powerful, but don’t forget to keep them stocked—running dry at the wrong moment could be fatal.

Several different enemies:
Headcrab

A small, fast, and terrifying parasite. This alien creature leaps at its victims, attempting to latch onto their heads and turn them into mindless zombies. While individually weak, they often attack in groups, making them a real threat in confined spaces.

Zombie

Once a human, now a grotesque husk controlled by a headcrab. These slow but relentless creatures will stop at nothing to tear you apart. Some are more resilient than others, and a well-placed shot is the only way to ensure they stay down for good.

Manhack

A compact, flying blade drone designed for one thing—shredding anything in its path. Fast, agile, and difficult to hit, Manhacks can quickly overwhelm an unprepared target. Keep your crowbar ready, or risk getting sliced to pieces.

Turret

A deadly automated defense system that locks onto movement and fires on sight. These sentry guns are stationary but highly dangerous, capable of cutting down anyone who enters their line of fire.

Tripmine

A lethal explosive trap, usually placed in doorways or narrow corridors. Triggering its laser sensor results in instant death.

Key Elements

Unforgiving Atmosphere – Experience a world plunged into chaos. Isolation, uncertainty, and the constant threat of death shape every moment of your journey.

Survival Mechanics – Combat is not just about shooting. Manage your ammunition carefully—you don’t find pre-loaded magazines, so you’ll have to refill them yourself. Every bullet counts.

Tactical Melee Combat – The crowbar isn’t just a weapon—it’s your lifeline. Use it to block enemy attacks, reducing incoming damage or even deflecting fatal blows.

Adaptive AI Enemies – Enemies are not just mindless obstacles; they react dynamically to your presence. Whether it’s the relentless pursuit of zombies, the ambush tactics of headcrabs, or the precision of turrets, every encounter is a fight for survival.

Deadly Environmental Hazards – The world itself is as dangerous as the creatures within it. Tripmines, automated turrets, and other hazards make every step forward a potential deathtrap.

Immersive Storytelling – Nothing is as it seems. Your reality shifts as you uncover disturbing truths behind the catastrophe. Are you fighting an alien invasion, or is the real enemy something much closer to home?

High-Risk Combat – Weapons are powerful, but only if used wisely. Careless shooting will leave you defenseless, forcing you to scavenge, plan, and make every shot matter.
