From now on, you can play Saboteur 2 online. Besides, it's totally free.
Board Game Arena (BGA), a community for online gamers, has already put the basic game Saboteur online in 2012. Thanks to its huge success, the developers were also interested in programming the expansion, Saboteur 2.
This expansion adds new characters and action cards, making the game a little bit more complex, but that's exactly what the players on BGA are looking for.
If you want to try the expansion before buying a boxed version or if you just want to play it for free, follow this link to BGA.
