**What is the Rage Virus?**
Rage Virus is a behavioural infection mod. It doesn't add new mobs, new structures, or new dimensions. What it adds is something much simpler and much harder to escape — a virus that spreads through the world's existing population and turns everything hostile-capable into a hunter.
One mob. That's how it starts. Somewhere in the world, without warning, a single mob becomes infected. You won't know where. You won't know what. The only hint you'll get is a quiet message that something doesn't feel right.
From there, it's up to the virus
-------------------------------------------------------------------------------------------
**How It Works**
Infected mobs — called Ragers — lose all their normal survival instincts. They don't flee. They don't avoid threats. They attack everything uninfected within range, and when they land a hit, there's a high chance the victim joins them. The infection spreads fast if left unchecked.
The virus progresses through three stages over time, each making Ragers faster, harder hitting, and more difficult to stop. A freshly infected mob is dangerous. A mob that's been a Rager for twenty minutes is something else entirely.
Patient Zero — the first infected mob — is treated differently from the start. It's stronger, faster, and carries a persistent regeneration effect that keeps it alive longer than it has any right to be. When it dies, the oldest surviving Rager inherits its role. There is always a Boss Rager. The outbreak always has a leader.
When Ragers run out of targets, they don't wander. They find you.
-------------------------------------------------------------------------------------------
**Key Features**
No new mobs — every Rager is a vanilla mob you already know, just wrong.
No block infection — the world stays intact, the population doesn't.
Behavioural spread — the virus moves through attacks, not proximity or blocks.
Three infection stages — power scales with time, not with spawn rates.
Boss Rager system — a persistent, regenerating leader with succession on death.
Passive mob immunity — cows, pigs, and chickens are prey, never Ragers.
Ranged mobs keep their range — skeleton Ragers still shoot, they just shoot at everything.
Infected Creepers won't blow up their allies — they'll wait for a clean shot.
Player immunity — you can't be infected, but you are always a target.
Atmosphere over UI — the outbreak communicates through sound, particles, and subtle screen effects rather than health bars and percentages.

**What to Expect**
Early on, you might not notice anything. The infection starts far from you and spreads quietly. The first sign is usually a sound — something off about the world.
By the time you see your first Rager, there are probably more you haven't found yet.
-------------------------------------------------------------------------------------------
**Compatibility**
Rage Virus is designed to work alongside other mods. Modded mobs that are eligible for infection will be treated as Ragers if hit. If a modded mob causes any issue during infection, the mod will skip it silently rather than crash.
Requires: NeoForge 21.4.x for Minecraft 1.21.4

**A Note on Design**
There are a lot of infection mods out there, and most of them are great at what they do. This one tries to do something a little different — instead of adding new threats to the world, it turns the world's existing population into the threat. Everything in a Rage Virus playthrough is something you've fought before. The virus just makes sure you can't rely on it behaving the way you expect.

**Known Issues (1.0.0)**
- The Boss Rager does not yet actively hunt the player when no
other targets are present. This is being investigated for 1.0.1.
- Newly infected mobs may briefly continue attacking their previous
target before switching to new uninfected prey. Being fixed in 1.0.1.
