Your science fiction troopers need a utility hovercraft to get around in. Here’s a nice paper model of just such a craft.
For Infinity and other science fiction games, here’s a paper model of a Chickenhawk dropship. It comes in a couple of different versions.
In the Noonday Sun is a set of rules for small unit actions, derived from another set called Slammer. The authors of Noonday write:
In the Noonday Sun is a set of wargame rules for skirmish games using miniatures. I intended from the start that Noonday Sun would be flexible and adaptable to different scenarios. I have intentionally kept it ‘loose’, particularly in areas like troop motivation and Hollywood heroics. Noonday Sun is meant to be fun! We use miniatures on the tabletop to represent men and women who might well be scared or heroic, angry or bored, professional or just hungry, above all they are unpredictable. When you play Noonday Sun, occasionally try to see things through your troops’ eyes. They are more than just disposable weapons delivery systems.
Harry Pratt’s Battlestar Galactica Starship Combat Rules are designed to recreate starship combat rules from the msot recent Galaxtica television shows.
I have to say that the fleet combat sequences in the series are absolutely spectacular, with those missles streaking through space and the ships burning up under multiple hits. Perhaps not the most scientifically valid, but spectacular nonetheless.
I absolutely love the Full Thrust starship rules. If you can’t get enought of the rules, there’s now a Full Thrust Wiki.
