Raptor: Call of the Shadows is a vertically scrolling shooter developed by Cygnus Studios and published by Apogee Software. Its working title was "Mercenary 2029". It was released on April 1, 1994 for MS-DOS compatible systems. The first episode of the game, "Bravo Sector", was distributed as shareware. The other two episodes were sold commercially. Plot "In the future a mercenary flying the [advanced] Raptor, is sent on interplanetary missions to [destroy] top competitors of MegaCorps." Episodes The game is divided into three "sectors": Bravo Sector, Tango Sector, and Outer Regions, all of which have sub-missions called "waves", making for a total of 27 levels (9 per sector). The full version of Raptor allows players to start out in any of the three campaigns, though playing them in order helps the player to more easily accumulate money for weapon and shield upgrades. Once a player beats a sector, they can replay it with all the money and weapons that they have accumulated. The difficulty is increased when the player does this however, e.g. if the player beats the sector on Rookie and replays it, the difficulty will be set to Veteran. The Bravo Sector is the most "generic" episode, with few features distinguishing each level. Starting at the coast and then moving inland, most of the targets are military bases and installations, and much of the terrain is barren land, with the occasional forests and rivers. Large oil silos feature prominently in the early waves, and a refinery (tank farm) is found in the second-last wave. In the final wave, the player flies offshore to destroy the Lithos Petroleum rig. (However, there is no background on why Lithos is the enemy, other than being suggested as a competitor of MegaCorps.) The Tango Sector is more distinctive, with each level following a different theme. These include a large water/chemical plant, farmland, jungle, city, and airbase. At the end, in the jungle after destroying an ancient temple, the player has to defeat a huge aircraft which splits into three modules. In Outer Regions, the player travels from different planets; they consist of a lunar body (moon), a red planet similar to Mars, an ice world, a volcanic world, and finally a space station. Tango Sector and Outer Regions each have a special "night wave" with its own theme music. The night level in the Tango Sector is a well-illuminated city in Wave
