Inspired by "Take The Station" I designed a scenario for 3 players. While "Take The Station" is fine, it is a better game for four players. But if you are four you can easily split up and play two regular games.
"Capture The Hostage" is played at a standard map but trianglular shaped play area. (That's not only because I love triangles.)

You may find the rules in a google document:

Have fun while reading and let me know how it played out, if you play it.
Sounds fun! I like the "Hot Potato" aspect of this scenario.
