Vassal is an online tabletop program that hs a moduel for Xwing, and an extension has been made for HotAC. (http://www.vassalengine.org/wiki/Module:Star_Wars:_X-Wing_Miniatures_Game Scroll down to 6.1 for HotAC, it's still compatible with recent releases.)
Heros of the Aturi Cluster is a cooperative campaign for Xwing, including simple AI for the imperial enemies.
I would like to find interested players capable of agreeing upon a day/time to run a modified campaign over vassal.
Suggested houserules:
Pooled XP
Expanded ship lists
All waves available
Improved Generic Enemies
-Tie fighters gain Comm Relays (and modified action tree) at player PS4, Juke at PS6, and a shield at PS8
-Starting at Player PS4, All Non-elite intercepters are elites at 2 less than normal Player Pilot Skill.
-Non-elite Tie Bombers have Extra munitions.
