BOARDING ACTIONS

When crews engage in direct ship-to-ship combat by physically entering enemy vessels, use these boarding rules.

Boarding Methods

There are four primary methods to initiate boarding:

1. Anchoring Weapons

A ship equipped with an anchoring weapon (grappler, tractor beam) can lock onto an adjacent enemy ship.

Gunnery DC: Target's AC
Effect on Success: Ships are anchored together. Neither ship can move until the anchor is released or destroyed. Boarding parties can transfer between ships.

2. Ramming

A pilot can intentionally collide with an enemy ship to allow boarding.

Flight DC: Target's AC
Effect on Success: Both ships take collision damage (see Environmental Hazards). Ships are considered adjacent for boarding purposes for 1 round.

3. Breaching Pods

Breaching pods are single-use boarding vessels launched at enemy ships.

Gunnery DC: Target's AC (breaching pods cannot penetrate active shields)
PCU Cost: 5 per pod
Effect on Success: Pod attaches to enemy hull. Boarding party of up to 4 creatures can enter the enemy ship next round.

4. Creature Injection

Starship-scale creatures with appropriate abilities can inject pathogens or smaller creatures into enemy vessels.

Special Attack DC: Target's TL
Effect on Success: Injected creatures/pathogens begin affecting the enemy ship's crew.

Boarding Combat Statistics

Boarding Attack Modifier

When a boarding party attempts to overcome ship defenses:

Boarding Attack = 1d20 + boarding party leader's Intimidation or Athletics modifier + size modifier

Size Modifier:

Boarding Party Size vs. Ship Complement	Modifier
Party is 50%+ of complement	+4
Party is 25-49% of complement	+2
Party is 10-24% of complement	+0
Party is 5-9% of complement	-2
Party is less than 5% of complement	-4

Boarding Rating (BR)

The target ship's defense against boarding.

BR = 10 + ship's level + security system bonus + crew quality modifier

Crew Quality Modifier:

Crew Type	Modifier
Elite military	+4
Professional	+2
Standard	+0
Skeleton crew	-2
Automated only	-4

Environment: Cramped shipboard corridors (difficult terrain, limited visibility)

Victory Conditions:

Attackers Win: Gain control of the boarded section; can attempt to take ship systems
Defenders Win: Repel boarders back to their ship or capture them

Security Systems

Security systems add to a ship's BR and provide additional defenses.

System	BR Bonus	BP Cost	Special
