Wing Commander is the first installment in Chris Roberts' science fiction space simulation franchise. The game was released in 1990.
Released by Origin Systems, the game was a marked departure from the standard formula, bringing space combat to a level approaching the Star Wars films.
Set in the year 2654 and characterized by Chris Roberts as "World War II in space", it featured a multi-national cast of pilots from the "Terran Confederation" flying missions against the predatory, aggressive Kilrathi, a feline warrior race.
Most impressively, cockpit performance affected gameplay: going above and beyond the call of duty resulted in medals, promotions in rank were awarded at regular intervals, and success or failure on certain critical missions would even decide the player's plot progress.
We take the role of a nameless pilot aboard the TCS Tiger's Claw, a Bengal-class Strike Carrier. We eventually lead a strike on the Kilrathi High Command star base in the Venice system. On the other hand, if we do not perform optimally, missions become increasingly defensive in nature and eventually the Claw is forced to retreat.
Technically, Wing Commander break some new ground as unlike X-Wing or Tie Fighter series, it don't use polygon graphics but use bitmap rotation and resize technique to create a 3D world, some sort like using Wolfenstein 3D technique, but in space.
