== Overview ==

A game about space travel will almost inevitably require rules for space combat. The rules presented here are meant to provide a relatively simple means of resolving space combat that doesn't depart too strongly from the Traveller Combat system.

'''Mneme Space Combat''' is a variant rule set for the Cepheus Engine system, designed to streamline space combat while maintaining tactical depth and narrative excitement.

== Key Features ==

; Use of a Map : Track ship positions and movement during encounters
; Order of Turns : Initiative-based action sequencing
; Clarified Encounter and Combat Ranges : Precise definitions of engagement distances
; Grouping Rolls : Streamlined mechanics for handling multiple ships or attacks
; Core Task Resolution System : 2d6-based mechanics adapted for space combat
; Only Players Roll, even for Adversaries : Reduces Referee workload

== Summary of Changes from Cepheus Engine SRD ==

=== Core Task Resolution Changes ===

; Target Number (TN) : Typically 8+, varies by circumstance
; How Effect is Calculated : Dice Roll + Dice Modifier - Target Number = Effect (minimum 1 on success)
; One Roll Opposed Checks Mechanics : Players roll against TN calculated as 8 + Adversary's DM
; Minimum Success Effect of 1 : A success always has at least Effect 1
; Double Effect Rolling 2 and 12 : Natural 12 doubles positive effect, natural 2 doubles negative effect

=== Superiority System ===

A Superiority dice modifier is added as a bonus or penalty based on relative resources, numbers, and preparation time between opposing forces.
