Attack Vector: Tactical
Attack Vector: Tactical (AV:T) is a space combat wargame published by Ad Astra Games. The game is consciously designed to model comparatively realistic space combat and eschew common conventions of space warfare. Attack Vector: Tactical is set in the "Ten Worlds," a region of space expanded ten parsecs from Sol. Some factors, unusual to the genre of space combat games, that AV:T includes: Beyond its physics model, is notable for being one of the few wargames that attempts true three dimensional movement. While prior attempts (BattleFleet Mars) have been made, most have failed in playability . AV:T handles three dimensionality with several play aids, such as the Attitude/Vector Information Display (AVID), which is a color-coded polar projection of a sphere fixed relative to the hexmap handling sighting angles and ship orientation for thrust, the Range/Angle Lookup Table (RALT), which is a table of the Pythagorean Theorem that's been color-coded to reflect bearing angles used by the AVID, and tilt blocks, box miniatures and stacking tiles for on-map display of ship orientation. Ten Worlds Universe. The Ten Worlds universe is designed around a hard science fiction paradigm. There are no  alien civilizations. All technology present is at the very least currently feasible, with the singular exception of FTL travel. Though its presence is acknowledged to permit extra-solar settings, it is limited to a degree rare to the genre. Normal space travel is realistic, meaning travel between planets is a matter of months or even years, not hours. FTL is only possible from a single point in any given star system (within a quarter AU of its sun), making it as much a destination to be reached as it is a means of reaching a destination. Different sets of routes  each require a specific variation of the device, limiting the effective range of any given interstellar craft. Each use of the device must be planned well in advance of a pre-decided time, meaning one cannot use it to quickly escape from combat. All these factors combine to eliminate its effect on gameplay, making it similar to the Alderson Drive of Jerry Pournelle's CoDominium Universe. Reception. The game itself won won the Origins Award in 2004 for "Best Miniatures Game".
