I have been working with Chris Nicole to bring back his original Slammer scifi miniatures rules and you can now grab the "Legacy" edition which is the original document in PDF format. Pay What You Want so please give generously (but responsibly!)

Response and feedback will be used to both tidy up and improve this version, but also work up a new, cool edition for a new generation to enjoy.

From the WGV page:

"The Slammer rules are usable for a range of Hollywood-inspired science fiction skirmish action, complete with big heroes, cool space troopers and bug eyed aliens.

Featuring a clever reaction table, the morale and well being of your troops will affect what actions they can perform each turn but gameplay still moves quite quickly.

A starting game can play well with a handful of characters on each side, while you can easily play with a platoon once you understand how the game works.

The rulebook currently clocks in at under 40 pages, giving all the basic stuff needed to play a game without a lot of waffling about. You are here to shoot bug eyed monsters right?"
