Pathway, the strategy adventure set in the 1930s from Robotality recently had a huge update if you need something to challenge you this is it.
Now when making a new game in Pathway, it gives you the option to make your profile a Hardcore Profile which can't be changed after. In this mode, the entire games plays as one long adventure with everything carrying over between sections. So if a character dies, they're gone. It also gives you all jeep upgrades and characters and higher difficulty.
This Hardcore Mode update came with a bunch of other smaller additions too. Including an extended difficulty option (not Hardcore but still harder than normal), more tooltips, 12 new weapons and new variations and some bug fixes.

I've enjoyed plenty of time in Pathway, even on the lower difficulty levels I personally find it quite challenging to deal with the combat and the events. The developer was quite positive about Linux support last we spoke too.
