This sourcebook details: organizations, alien races and individual aliens for use in Champions superhero campaigns. All of the standard comic superhero alien types are represented: the lone survivor/lost/amnesiac/banished, stranded outposts, criminal/vigilant visitors, stellar empires, body/identity snatchers, and the overwhelming horde of innocent intent. There is also a semi-comical group of anti-alien enforcers, and a seriously pro-alien lobbying group/research center/safe house. Any superhero GM would benefit from the information within.

Of course the information is easily used with any HERO sys game and other games of different genre. Star Hero (or was it Space Hero)/scifi would be a logical user of the book as a whole. Both colorful NPC individuals and races are provided. There are hooks to stellar empires and interstellar threats. In fact, this is as much a Star Hero supplement as one for Champions. Any scifi campaign will find some universe expanding and detailing ideas in these pages.

Fantasy HERO and other fantasy campaigns could benefit in many ways. Visits from hi-tech aliens is an old Fantasy standard: conquerors, explorers, exploiters. Four of the races presented (Arcane, Masq, Karrg, Tyrixx) would make excellent native races in a fantasy campaign, escaping some of the "old standards" like orcs, goblins, elves and dwarves. The Pantheon, a group of alien "god-imposters", would really add some twists to a campaign where religion is a factor. No Spelljammer/Dark Space GM will be able to resist pirate Capt. Richaal's, Galactic Marauders.

Aliens have always had their place in horror campaigns and several of the entries within Alien Enemies fit especially well. There are mindless zombies, ravenous amphibians, insect warriors (ala Aliens) and impersonators.

Post Holocaust worlds are also visited by: settlers, conquerors, explorers and exploiters from other planets.

I'm sure there are tie-ins to every genre. The fact is, I find the $12 cover price steep (but I'm cheap), if you can find it for under $10 you can't go wrong if you buy it.
