In 20 pages are packed 16 pages of information. Unlike many small PDF’s, this one includes clickable links in the table of contents. While not necessarily needed in so few pages, it is much appreciated!
The classes presented are alien, astromancer, engineer, lost worlder, scoundrel, and warp ninja.
Aliens are a generic class to cover any kind of alien you can imaging. 8 abilities are suggested, from which the player picks one. There is also an option to convince the GM to let you make up an ability. These would also make good generic NPC aliens.
Astromancers remind me a bit of illusionists, but have some very interesting “Quantum Formulae” that they can use. Many of the names of these re-worked spells give a science fiction flair to otherwise standard and well known spells. There are a few new “spells” here, along with some interesting abilities.
Engineers read like a cross between MacGiver and Mr. Scott. With abilities that allow them to do various kinds of “save the day” things. I really love the techno-babble chart for generating random terms, such as “quantum radiation capacitor”.
The lost worlder is a “barbarian in spaaaace!” The don’t use high tech gear, but have a chance to randomly push buttons to make something work, with an equal chance of catastrophic failure. One of the abilities is extra resistance to disease and poison, with a bonus on such saving throws. I am reminded of Leela from Dr. Who, and similar such characters.
Scoundrels are an obvious homage to Han Solo, and other stereotypical characters in all manner of fiction. One of their skills is “know a guy”, giving them a chance to know someone, not necessarily friendly. This single page sums up what most of us envisage a scoundrel to be.
Warp Ninjas are an interesting idea. It takes ninjas and crosses them with a dash of science fiction, and uses a black hole to power their abilities. Two of their abilities are dangerous and actually cause damage if used. They are powerful, but a bad roll could mean it’s time to roll up a new character.
Finally, the last page of game material is a set of charts for Random Humanoid Species Appearance Charts, for skin color, hair, ears, eyes, and miscellaneous features. These charts use a d6, three of them use a d8, and a d20, so 5 dice, if the d8’s are specified, can roll a random creature quickly.
The simplicity of each class fits right in with the overall theme of White Star.
