Aliens vs Predator Mod — Reference

Mobs: The Xenomorphs

Xenomorphs are the primary antagonists of the mod. They operate under a hive mind, led by a Queen, and follow a strict biological lifecycle.

The Lifecycle

1. Ovomorph (Egg): Naturally spawns in hives. When a host approaches, it opens to release a Facehugger.
2. Facehugger: A parasitic entity that attaches to the head of a host (player or mob). It implants an embryo and then dies.
3. Chestburster: After a 5-minute gestation period, the larva erupts from the host's chest, killing them instantly.
4. Adult: The Chestburster grows into an adult caste based on the host type (e.g., a Drone from a human, a Runner from a cow/horse).

Xenomorph Castes

Variants

• Nether Xenomorphs: Fire-resistant variants found in the Nether.
• Aberrant Xenomorphs: Rare, gold-tinted variants with increased stats.
• Irradiated Xenomorphs: Glowing variants that deal radiation damage over time.

Mobs: The Yautja (Predators)

The Yautja are elite hunters that spawn in Jungle and Forest biomes. They are neutral unless provoked or if the player is deemed a "worthy" hunt.

Behavior and Mechanics

• Cloaking: Predators use active camouflage to remain nearly invisible. They decloak loudly when attacking.
• Honor System: Predators follow a code. Killing "unworthy" targets (unarmed players, children, or peaceful animals) results in "Bad Blood" status, causing other Predators to become hostile toward the player.
• Mask Removal: When a Predator's health drops below 50%, it may remove its bio-mask, revealing its mandibles and increasing its aggression.

Predator Equipment

• Plasma Caster: A shoulder-mounted energy weapon that fires explosive plasma bolts.
• Wrist Blades: Retractable blades used for high-damage melee combat.
• Smart Disc: A throwable weapon that can be guided and returns to the user.

Items and Equipment

Survival in the AvP mod requires specialized gear. Most advanced items are crafted using the Assembler.

Weapons

• M41A Pulse Rifle: The standard-issue Marine firearm. Uses 10mm Explosive Tipped Caseless ammunition.
• M56 Smartgun: A heavy, auto-targeting machine gun that requires a specialized vest to operate.
• M240 Incinerator: A flamethrower effective at clearing hives and destroying Ovomorphs.
• Combi-Stick: A Yautja spear that can be thrown or used in melee.

Armor and Vision Modes

• Marine Armor: High physical protection with a built-in shoulder lamp.
• Predator Armor: Grants access to vision modes when the helmet is worn. Press 'V' to cycle modes:
• Thermal Vision: Highlights warm-blooded mobs (Humans, Animals).
• Electromagnetic Vision: Highlights Xenomorphs and synthetic life.
• Normal Vision: Standard view with HUD overlays.

Tools

• Motion Tracker: Detects movement within a 30-block radius, emitting a rhythmic ping that increases in frequency as threats approach.
• Supply Crate: Can be found in structures; contains ammunition, medical supplies, and food.

Blocks and Industrial Mechanics

The mod introduces a complex industrial system focused on power generation and base defense.

Power System

Electronic blocks require Voltage (V) to function. Power is transmitted through Power Lines. * Solar Panels: Generate low voltage during the day. * Repulsion Generator: A high-output generator that provides constant power but requires expensive materials to craft. * Power Cell: Acts as a battery to store excess voltage for nighttime or emergency use.

Technical Blocks

• Assembler: A 3x3 automated crafting table used for high-tier technology.
• Sentry Turret: An automated defense system. Requires power and a nearby ammo crate to function. It can be configured to target specific species via a Terminal.
• Blast Doors: Heavy, reinforced doors that can only be opened with power or a Security Access Tuner.

World Generation

• Ores: Titanium, Copper, Aluminum, Lithium, and Silica are added to the Overworld and modded dimensions.
• Hive Resin: A biological block spread by Xenomorphs. It slowly converts surrounding stone and dirt into hive territory.
