This is "Breach: Starship Duels" just slightly smaller. The tiles are reduced to the size of the Pocket Tactics/Pocket Dungeon sizes, which allows the user to user the Pocket Tactics trays. I've used the solid trays here, despite more plastic, because I like the contrast on the hollow tiles. I've also merged all the rulebooks, and did a little reformating/editing. Hopefully I didn't leave anything out. I didn't include the Hazard or Utility miniatures, deciding to just use the tiles since this game is supposed to be portable. Lastly, I haven't printed the box yet... I'll update it if I find out its too small. Many things to the folks at Ill Gotten Games ( http://www.illgottengames.net/ ) for the original game, and being so cool about sharing it. Enjoy!
