This version is fully up to date with all current releases including both Rebel Huge ships and Wave 4, and all spoiled Wave 5 and Rebel Aces content released so far.
BattleScribe is a generic list-building program (or an app for Android or IOS). You can get the PC or Mac version free at www.battlescribe.net (there are also links to download the mobile versions - also free - from the appropriate app stores).
Once you have the program, the file I posted lets you build X-Wing lists in BattleScribe. At the same website (www.battlescribedata.appspot.com) you can get files for lots of other games like Warhammer 40,000, Warhammer Fantasy, War Machine, etc. BattleScribe is great if you play multiple war games because you can use one program to manage all your lists in one format. Plus, it is easy to use and the apps don't require you to be online, so you can edit lists anytime, anywhere. It is easy to transfer lists between desktop/app, send lists to friends, or export in various formats. It has been my favorite list builder for a long time and I am excited to be keeping the X-Wing files updated.
