Miniature wargame science fiction skirmish rules. 5150: What is it? - Extract from the rules: 5150 is a game of sci-fi skirmish warfare. The rules handle fast and furious firefights set in the far future. If all you want to do is play “one up” unrelated battles on the tabletop you can do just that. But if you want, 5150 can be more than just a wargame. 5150 thrusts you into a universe populated by both humans and aliens. Real aliens. Not just characters with a number changed here or there to make them "tougher" but real aliens that act differently. 5150 starts you off in the middle of the action. Choose whom you are and what you want to do. Star Army soldier commanding a military formation sound good? Maybe a mercenary making ends meet by salvaging equipment on far off planets? How about an adventurer, coming and going as you please always in search of that one big "find" that’ll make you famous? Heck, you can even be a blue-skinned alien if you choose! With 5150 you’re only limited by your imagination. If you can imagine it you can do it. 5150 provides a changing universe to campaign in. Not only your actions but also the actions of those beyond your control help shape your life. But like in real life first you must survive before you thrive as you try to establish yourself and your followers as a force to be reckoned with. Gain experience and skills as you successfully move through the galaxy. Find friends; make enemies, its all there in 5150. As time passes challenges change and it will take a combination of tactics and strategy to succeed. And a little luck won’t hurt either! If you’ve played Chain Reaction: Fast and Furious Firefights 2.0, All Things Zombie, or Nuts! to name a few the mechanics in 5150 will be familiar but if you haven’t don’t worry. 5150 is a stand-alone game, easy to learn and fun to play.

The catalogue lists 5150 for ages 12 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone.
