Pollo, unfortunately you are right 
This project was so big in general. So much weapons and vehicles. The game has a destruction system, you can blow up every house and even terraform the terrain.
The soldiers have a gesture system with sensefull (and nonsense) gestures for nonverbal communication and, and, and…
The gamecompany (Wings Simulation) pushed the releasedate again and again.
And in the end, they released a seriously buggy version: “Söldner - Secret Wars”.
I never heard about a relaunch of a game, but they did it: “Söldner - Reloaded”.
Anyway, short after release, Jowood closed the Company, but finished the Addon “Söldner - Marine Corps”.
The idea behind the game is good, no question. But I guess Players prefer a tank that doesn’t turn upside down, after hitting a tree, instead of choosing between 73 different vehicles.
Did I really say this? nono, Developers: DO AS MANY VEHICLES AS POSSIBLE IN YOUR GAMES!!!
Anyway, we did our best to make this game cool, and were truely dissapointed that it fails.
December: thanks 
cheers
