1. Get the game and install it
I'ts hard to get a physical copy, specially when it falls under the "abandonware" category. Objetivo España is a standalone expansion.
2. Install the patch 1.1
Without it, the game will work very fast and some skirmish maps won't work at all. It fixed both issues for me for both Sombras de Guerra and Objetivo España.
3. Play
Don't expect a great game. But it should work, at least on win10.
