Starcraft Tactical Miniatures Combat
The Starcraft Tactical Miniatures Combat rules are based on the world of the classic video game. I suppose you could use miniatures from the board game to play.
Tacship Space Fighter Combat Rules
Tacship is a set of free wargames rules for space combat by John Tuffley. He writes:
Tacship is a simplified fast-play rules system for simulating combat between manned space fighters. The game may be played on a hex grid map or on a plain table area by substituting inches for hexes and measuring turns in 60 degree increments (the same as a one hexside facing change). Fighter models should be mounted on stands, preferably with a one inch hex base, if a grid is being used.
Unbreakable Future Ground Combat Miniatures Rules
Unbreakable is a set of free wargames rules for
a game of futuristic ground combat for 2 players. Each player assembles a platoon of crawlers, walkers, and powered armor squads and equips them with nukes, stasis rays, lasers, and more. Then the platoons meet in combat where they unleash terrible powers of overwhelming destruction. Fortunately, no one gets hurt. Thanks to amazing leaps in materials technology, the battlefield of the future will no longer be a dangerous place (for the combatants).
Crimson Dust Science Fiction Wargames Rules
Crimson Dust is a new set of science fiction wargames rules. The author writes:
Crimson Dust (not to be confused with Crimson Dusk) is a sci-fi skirmish game using mutliple D6 rolls to establish the results of shooting moving, etc. Its also a turnless game with players activating models or using a leader groups of models in sequence, being turnless means you can keep activating the same model whilst your opponent for example activates all of their models, as opposed to variations of ‘I go – you go’. This is significantly more detailed game than Crimson Dusk, and has very different mechanics, it been an very exciting project to work on. in addition we’ve been given permission to use some of the art of ‘Juddeski’ who is a young artist known on several forums, his artwork will come to decorate the internal pages of the rule book.
