Söldner: Secret Wars - often referred as Soldner, Soeldner, SSW or SMC - is a computer game, developed by Wings Simulations and published in May 2004 by JoWood Productions. The game can be played in first- or third-person. Players can control ground vehicles, planes, VTOLs and helicopters.
The game is made to be played online, with the single-player campaign used for training.
The game and the expansion set Marine Corps were re-released together in North America by Evolved Games (Take2 Interactive) in May 2006, renamed to Semper Fidelis: Marine Corps to avoid previous bad press about Söldner. Marketing text from the original Söldner release was re-cycled with no effort from JoWooD to promote the new release on its own merits.
