Raptor: Call of the Shadows
The game takes place in the future where you are a mercenary flying the Raptor fighter, you are sent to interplanetary missions to destroy top competitors of MegaCorps.
The game is divided into three "sectors": Bravo Sector, Tango Sector, and Outer Regions, all of which have nine 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. This game was re-released in 2010 by DotEMU as native Windows game and in 2015 for Steam. The version provided for free contains only the first Shareware sector.
